Previously indices were tightly bound to a particular Cogl vertex buffer
but we would like to be able to share indices so now we have
cogl_vertex_buffer_indices_new () which returns a CoglHandle.
In particular we could like to have a shared set of indices for drawing
lists of quads that can be shared between the pango renderer and the
Cogl journal.
cogl_enable_depth_test and cogl_enable_backface_culling have been renamed
and now have corresponding getters, the new functions are:
cogl_set_depth_test_enabled
cogl_get_depth_test_enabled
cogl_set_backface_culling_enabled
cogl_get_backface_culling_enabled
Originally cogl_vertex_buffer_add_indices let the user pass in their own unique
ID for the indices; now the Id is generated internally and returned to the
caller.
It's now possible to add arrays of indices to a Cogl vertex buffer and
they will be put into an OpenGL vertex buffer object. Since it's quite
common for index arrays to be static it saves the OpenGL driver from
having to validate them repeatedly.
This changes the cogl_vertex_buffer_draw_elements API: It's no longer
possible to provide a pointer to an index array at draw time. So
cogl_vertex_buffer_draw_elements now takes an indices identifier that
should correspond to an idendifier returned when calling
cogl_vertex_buffer_add_indices ()
Setting up layer combine functions and blend modes is very awkward to do
programatically. This adds a parser for string based descriptions which are
more consise and readable.
E.g. a material layer combine function could now be given as:
"RGBA = ADD (TEXTURE[A], PREVIOUS[RGB])"
or
"RGB = REPLACE (PREVIOUS)"
"A = MODULATE (PREVIOUS, TEXTURE)"
The simple syntax and grammar are only designed to expose standard fixed
function hardware, more advanced combining must be done with shaders.
This includes standalone documentation of blend strings covering the aspects
that are common to blending and texture combining, and adds documentation
with examples specific to the new cogl_material_set_blend() and
cogl_material_layer_set_combine() functions.
Note: The hope is to remove the now redundant bits of the material API
before 1.0
The CoglTexture constructors expose the "max-waste" argument for
controlling the maximum amount of wasted areas for slicing or,
if set to -1, disables slicing.
Slicing is really relevant only for large images that are never
repeated, so it's a useful feature only in controlled use cases.
Specifying the amount of wasted area is, on the other hand, just
a way to mess up this feature; 99% the times, you either pull this
number out of thin air, hoping it's right, or you try to do the
right thing and you choose the wrong number anyway.
Instead, we can use the CoglTextureFlags to control whether the
texture should not be sliced (useful for Clutter-GST and for the
texture-from-pixmap actors) and provide a reasonable value for
enabling the slicing ourself. At some point, we might even
provide a way to change the default at compile time or at run time,
for particular platforms.
Since max_waste is gone, the :tile-waste property of ClutterTexture
becomes read-only, and it proxies the cogl_texture_get_max_waste()
function.
Inside Clutter, the only cases where the max_waste argument was
not set to -1 are in the Pango glyph cache (which is a POT texture
anyway) and inside the test cases where we want to force slicing;
for the latter we can create larger textures that will be bigger than
the threshold we set.

Print out the cursor and selection positions in order to verify

This is a likely candidate for a conformance test unit as well.
The picking test has two configurables: the number of actors and
the number of events per frame. It makes sense to have them as
command line options to test with multiple configurations without
having to change defines and recompile.
COGLenum, COGLint and COGLuint which were simply typedefs for GL{enum,int,uint}
have been removed from the API and replaced with specialised enum typedefs, int
and unsigned int. These were causing problems for generating bindings and also
considered poor style.
The cogl texture filter defines CGL_NEAREST and CGL_LINEAR etc are now replaced
by a namespaced typedef 'CoglTextureFilter' so they should be replaced with
COGL_TEXTURE_FILTER_NEAREST and COGL_TEXTURE_FILTER_LINEAR etc.
The shader type defines CGL_VERTEX_SHADER and CGL_FRAGMENT_SHADER are handled by
a CoglShaderType typedef and should be replaced with COGL_SHADER_TYPE_VERTEX and
COGL_SHADER_TYPE_FRAGMENT.
cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and
cogl_shader_is_compiled. More getters can be added later if desired.
With the recent change to internal floating point values, ClutterUnit
has become a redundant type, defined to be a float. All integer entry
points are being internally converted to floating point values to be
passed to the GL pipeline with the least amount of conversion.
ClutterUnit is thus exposed as just a "pixel with fractionary bits",
and not -- as users might think -- as generic, resolution and device
independent units. not that it was the case, but a definitive amount
of people was convinced it did provide this "feature", and was flummoxed
about the mere existence of this type.
So, having ClutterUnit exposed in the public API doubles the entry
points and has the following disadvantages:
- we have to maintain twice the amount of entry points in ClutterActor
- we still do an integer-to-float implicit conversion
- we introduce a weird impedance between pixels and "pixels with
fractionary bits"
- language bindings will have to choose what to bind, and resort
to manually overriding the API
+ *except* for language bindings based on GObject-Introspection, as
they cannot do manual overrides, thus will replicate the entire
set of entry points
For these reason, we should coalesces every Actor entry point for
pixels and for ClutterUnit into a single entry point taking a float,
like:
void clutter_actor_set_x (ClutterActor *self,
gfloat x);
void clutter_actor_get_size (ClutterActor *self,
gfloat *width,
gfloat *height);
gfloat clutter_actor_get_height (ClutterActor *self);
etc.
The issues I have identified are:
- we'll have a two cases of compiler warnings:
- printf() format of the return values from %d to %f
- clutter_actor_get_size() taking floats instead of unsigned ints
- we'll have a problem with varargs when passing an integer instead
of a floating point value, except on 64bit platforms where the
size of a float is the same as the size of an int
To be clear: the *intent* of the API should not change -- we still use
pixels everywhere -- but:
- we remove ambiguity in the API with regard to pixels and units
- we remove entry points we get to maintain for the whole 1.0
version of the API
- we make things simpler to bind for both manual language bindings
and automatic (gobject-introspection based) ones
- we have the simplest API possible while still exposing the
capabilities of the underlying GL implementation
There were several functions I believe no one is currently using that were
only implemented in the GL backend (cogl_offscreen_blit_region and
cogl_offscreen_blit) that have simply been removed so we have a chance to
think about design later with a real use case.
There was one nonsense function (cogl_offscreen_new_multisample) that
sounded exciting but in all cases it just returned COGL_INVALID_HANDLE
(though at least for GL it checked for multisampling support first!?)
it has also been removed.
The MASK draw buffer type has been removed. If we want to expose color
masking later then I think it at least would be nicer to have the mask be a
property that can be set on any draw buffer.
The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes
have been moved up into cogl.h since they are for managing global Cogl state
and not for modifying or creating the actual offscreen buffers.
This also documents the API so for example desiphering the semantics of
cogl_offscreen_new_to_texture() should be a bit easier now.
The units in the Timeline test suite just rely on the timeline
being a timeout automatically advanced by the main loop. This
is not the case anymore, since the merge of the master-clock.
To make the test units work again we need to "emulate" the master
clock without effectively having a stage to redraw; we do this
by creating a frame source and manually advancing the timelines
we create for test purposes, using the advance_msecs() "protected"
method.
With the change in commit 87e4e2 painting of hidden source actors
in ClutterClone was fixed. This commit changes the test-actor-clone
to visually verify this.
Setting the wrap mode on the PangoLayout seems to have disappeared
during the text-actor-layout-height branch merge so this brings it
back. The test for this in test-text-cache no longer needs to be
disabled.
We also shouldn't set the width on the layout if there is no wrapping
or ellipsizing because otherwise it implicitly enables wrapping. This
only matters if the actor gets allocated smaller than its natural
size.
Bug 1138 - No trackable "mapped" state
* Add a VISIBLE flag tracking application programmer's
expected showing-state for the actor, allowing us to
always ensure we keep what the app wants while tracking
internal implementation state separately.
* Make MAPPED reflect whether the actor will be painted;
add notification on a ClutterActor::mapped property.
Keep MAPPED state updated as the actor is shown,
ancestors are shown, actor is reparented, etc.
* Require a stage and realized parents to realize; this means
at realization time the correct window system and GL resources
are known. But unparented actors can no longer be realized.
* Allow children to be unrealized even if parent is realized.
Otherwise in effect either all actors or no actors are realized,
i.e. it becomes a stage-global flag.
* Allow clutter_actor_realize() to "fail" if not inside a toplevel
* Rework clutter_actor_unrealize() so internally we have
a flavor that does not mess with visibility flag
* Add _clutter_actor_rerealize() to encapsulate a somewhat
tricky operation we were doing in a couple of places
* Do not realize/unrealize children in ClutterGroup,
ClutterActor already does it
* Do not realize impl by hand in clutter_stage_show(),
since showing impl already does that
* Do not unrealize in various dispose() methods, since
ClutterActor dispose implementation already does it
and chaining up is mandatory
* ClutterTexture uses COGL while unrealizable (before it's
added to a stage). Previously this breakage was affecting
ClutterActor because we had to allow realize outside
a stage. Move the breakage to ClutterTexture, by making
ClutterTexture just use COGL while not realized.
* Unrealize before we set parent to NULL in clutter_actor_unparent().
This means unrealize() implementations can get to the stage.
Because actors need the stage in order to detach from stage.
* Update clutter-actor-invariants.txt to reflect latest changes
* Remove explicit hide/unrealize from ClutterActor::dispose since
unparent already forces those
Instead just assert that unparent() occurred and did the right thing.
* Check whether parent implements unrealize before chaining up
Needed because ClutterGroup no longer has to implement unrealize.
* Perform unrealize in the default handler for the signal.
This allows non-containers that have children to work properly,
and allows containers to override how it's done.
* Add map/unmap virtual methods and set MAPPED flag on self and
children in there. This allows subclasses to hook map/unmap.
These are not signals, because notify::mapped is better for
anything it's legitimate for a non-subclass to do.

Bug 1513 - Allow passing in ClutterPickMode to
clutter_stage_get_actor_at_pos()
At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL
internally to find an actor. It would be useful to allow passing in
ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller
can specify CLUTTER_PICK_REACTIVE as a criteria.
Three tests are now performed on the picked squares. First there is no
covering actor which is the same as the original test. Then there is a
hidden covering actor which should not affect the results. Finally
there is a covering actor with a clip set on it so that only actors
at the borders of the stage should be pickable.
The wrap mode sub-test inside the ClutterText layout cache test
unit has been broken by the recent changes inside the Text actor.
The sub-test itself might require tweaking.
The cogl_is_* functions were showing up quite high on profiles due to
iterating through arrays of cogl handles.
This does away with all the handle arrays and implements a simple struct
inheritance scheme. All cogl objects now add a CoglHandleObject _parent;
member to their main structures. The base object includes 2 members a.t.m; a
ref_count, and a klass pointer. The klass in turn gives you a type and
virtual function for freeing objects of that type.
Each handle type has a _cogl_##handle_type##_get_type () function
automatically defined which returns a GQuark of the handle type, so now
implementing the cogl_is_* funcs is just a case of comparing with
obj->klass->type.
Another outcome of the re-work is that cogl_handle_{ref,unref} are also much
more efficient, and no longer need extending for each handle type added to
cogl. The cogl_##handle_type##_{ref,unref} functions are now deprecated and
are no longer used internally to Clutter or Cogl. Potentially we can remove
them completely before 1.0.
There is no need for a custom hsl to rgb converter since Clutter implements
this logic; originally it wasn't quite as optimal, but that has now been
fixed.
Using test-cogl-vertex-buffer as a test case which is CPU bound due to
hls -> rgb conversions this alternative algorithm looked to be ~10%
faster when tested on an X61s Lenovo.
The test is a sanity check that dynamic updating of vertex data via the cogl
vertex buffer api works and has reasonable performance. (though it can't be
considered a well designed benchmark since it wastes casual amounts of CPU
time simply choosing pretty colors.)
The code also aims to demonstrate one way of creating, updating and efficiently
drawing a quad mesh structure via the vertex buffer api which could be applied
to lots of different use cases.
Only have load-data-async and load-async properties, both are construct
only and the latter adds the former load-size-async behavior on top of
load-data-async.
The fog and perspective API is currently split in two parts:
- the floating point version, using values
- the fixed point version, using structures
The relative properties are using the structure types, since they
are meant to set multiple values at the same time. Instead of
using bare values, the whole API should be coalesced into two
simple calls using structures to match the GObject properties.
Thus:
clutter_stage_set_fog (ClutterStage*, const ClutterFog*)
clutter_stage_get_fog (ClutterStage*, ClutterFog*)
clutter_stage_set_perspective (ClutterStage*, const ClutterPerspective*)
clutter_stage_get_perspective (ClutterStage*, ClutterPerspective*)
Which supercedes the fixed point and floating point variants.
More importantly, both ClutterFog and ClutterPerspective should
using floating point values, since that's what get passed to
COGL anyway.
ClutterFog should also drop the "density" member, since ClutterStage
only allows linear fog; non-linear fog distribution can be achieved
using a signal handler and calling cogl_set_fog() directly; this keeps
the API compact yet extensible.
Finally, there is no ClutterStage:fog so it should be added.
The ClutterColor API has some inconsistencies:
- the string deserialization function does not match the rest of
the conversion function naming policy; the naming should be:
clutter_color_parse() -> clutter_color_from_string()
and the first parameter should be the ClutterColor that will
be set from the string, not the string itself (a GDK-ism).
- the fixed point API should not be exposed, especially in the
form of ClutterFixed values
- the non-fixed point HLS conversion functions do not make any
sense. The values returned should be:
hue := range [ 0, 360 ]
luminance := range [ 0, 1 ]
saturation := range [ 0, 1 ]
like the current fixed point API does. Returning a value in
the [ 0, 255 ] range is completely useless
- the clutter_color_equal() should be converted for its use inside
a GHashTable; a clutter_color_hash() should be added as well
- the second parameter of the clutter_color_shade() function should
be the shading factor, not the result (another GDK-ism). this way
the function call can be translated from this:
color.shade(out result, factor)
to the more natural:
color.shade(factor, out result)
This somewhat large commit fixes all these issues and updates the
internal users of the API.
The libdisable-npots library is just used as a helper as part of
make test so it should not be installed.
If noinst_* is used then automake will generate a static library but
this won't work with LD_PRELOAD so we then need an extra custom rule
to link that into a shared library. The custom rule uses the $(LINK)
Makefile var which gets put in the Makefile because of the static
library. We pass libtool a stub -rpath option which causes it to
generate a shared library.
The test now explicitly reads back from the framebuffer to sanity check that
texturing is happening as expected, and it now uses a fixed 2x2 texture instead
of redhand.png since redhand.png doesn't have a power of two size which can
cause the vertex buffer code to complain on hardware not supporting npot
textures.
The TEST_CONFORM_TODO macro is a simple placeholder macro that
adds the test function to the "/todo" namespace and skips the
test.
It can be used for tests that are known to fail because of bugs
that haven't been fixed yet, or because of features not yet
implemented.
test-vertex-buffer-configuous now needs redhand.png so it should be
copied in to the build directory. This is copied from similar code in
the tests/interactive Makefile.
ClutterModel has an interactive test but lacks a conformance
unit for automatic testing.
This is the beginning of that unit, which covers the population
and iteration over a ListModel.
Sometimes a test unit should not be executed depending on a
condition. It would be good to have a macro doing this, along
with TEST_CONFORM_SIMPLE().
Additionally, the skipped unit should be added to a specific
namespace, so that any coverage report will be able to catch it.
For this reason, here's TEST_CONFORM_SKIP() which follows the
syntax:
TEST_CONFORM_SKIP (condition, namespace, function);
If condition evaluates to FALSE the test is skipped and the
unit added to the "/skipped" namespace.
The test no longer requires an XID argument to run; instead it creates its
own X Window. The test now also aims to demonstrate whether mipmapping is
working, and clearly informs you if fallbacks are being used for GLX tfp.
Fixes some blending issues when using color arrays since we were
conflicting with the cogl_enable state + fixes a texture layer
validation bug.
Adds a basic textured triangle to test-vertex-buffer-contiguous.
The test simply creates an odd sized texture with different colors at
each of the four corners. It then renders the texture and verifies
that the colors are the expected values. This should help ensure that
the sliced texture rendering code is working properly.
The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.
Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.
See bug 1428:
http://bugzilla.openedhand.com/show_bug.cgi?id=1428
This makes it consistent with cogl_rectangle_with_{multi,}texture_coords.
Notably the reason cogl_rectangle_with_{multi,}texture_coords wasn't changed
instead is that the former approach lets you describe back facing rectangles.
(though technically you could pass negative width/height values to achieve
this; it doesn't seem as neat.)
Bug 1349 - Using the anchor point to set the scale center is messy
The branch adds an extra center point for scaling which can be used
for example to set a scale about the center without affecting the
position of the actor.
The scale center can be specified as a unit offset from the origin or
as a gravity. If specified as a gravity it will be stored as a
fraction of the actor's size so that the position will track when the
actor changes size.
The anchor point and rotation centers have been modified so they can
be set with a gravity in the same way. However, only the Z rotation
exposes a property to set using a gravity because the other two
require a Z coordinate which doesn't make sense to interpret as a
fraction of the actor's width or height.
Conflicts:
clutter/clutter-actor.c
During the upgrade to cogl material, test-backface-culling was
switched to use cogl_rectangle instead of cogl_texture_rectangle to
draw the textures. However, cogl_rectangle takes a width and height
instead of the the top-left and bottom-right vertices so the
rectangles were being drawn in the wrong place.

ClutterClone supercedes ClutterCloneTexture, since it can clone
every kind of actor -- including composite ones.
This is another "brain surgery with a shotgun" kind of commit: it
removes CloneTexture and updates every test case using CloneTexture
to ClutterClone. The API fallout is minimal, luckily for us.
This glues CoglMaterial in as the fundamental way that Cogl describes how to
fill in geometry.
It adds cogl_set_source (), which is used to set the material which will be
used by all subsequent drawing functions
It adds cogl_set_source_texture as a convenience for setting up a default
material with a single texture layer, and cogl_set_source_color is now also
a convenience for setting up a material with a solid fill.
"drawing functions" include, cogl_rectangle, cogl_texture_rectangle,
cogl_texture_multiple_rectangles, cogl_texture_polygon (though the
cogl_texture_* funcs have been renamed; see below for details),
cogl_path_fill/stroke and cogl_vertex_buffer_draw*.
cogl_texture_rectangle, cogl_texture_multiple_rectangles and
cogl_texture_polygon no longer take a texture handle; instead the current
source material is referenced. The functions have also been renamed to:
cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords
and cogl_polygon respectivly.
Most code that previously did:
cogl_texture_rectangle (tex_handle, x, y,...);
needs to be changed to now do:
cogl_set_source_texture (tex_handle);
cogl_rectangle_with_texture_coords (x, y,....);
In the less likely case where you were blending your source texture with a color
like:
cogl_set_source_color4ub (r,g,b,a); /* where r,g,b,a isn't just white */
cogl_texture_rectangle (tex_handle, x, y,...);
you will need your own material to do that:
mat = cogl_material_new ();
cogl_material_set_color4ub (r,g,b,a);
cogl_material_set_layer (mat, 0, tex_handle));
cogl_set_source_material (mat);
Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use
cog_rectangle_with_texure_coords since these are the coordinates that
cogl_rectangle will use.
For cogl_texture_polygon; as well as dropping the texture handle, the
n_vertices and vertices arguments were transposed for consistency. So
code previously written as:
cogl_texture_polygon (tex_handle, 3, verts, TRUE);
need to be written as:
cogl_set_source_texture (tex_handle);
cogl_polygon (verts, 3, TRUE);
All of the unit tests have been updated to now use the material API and
test-cogl-material has been renamed to test-cogl-multitexture since any
textured quad is now technically a test of CoglMaterial but this test
specifically creates a material with multiple texture layers.
Note: The GLES backend has not been updated yet; that will be done in a
following commit.
Step two: rename the object and its methods.
While we're at it, adhere more strictly to the coding style
practises; rename :clone-source to :source; add a setter method
for the :source property; take a reference on the source actor
to avoid it disappearing while we're still accessing it.
This removes a lot of code from test-cogl-primitives to make it easier
to follow. The TestCoglBox custom actor has gone and instead a blank
ClutterGroup is created with a paint signal handler.
Instead of rendering constantly and updating when a GTimer elapses a
second, a ClutterTimeline is used with 1 fps and a new redraw is
queued every frame.
The custom main loop is replaced with a regular call to clutter_main.
This fixes the close button of the stage window so you can quit
without having to press Ctrl+C.
The rotation centers are now tested in a similar way to the anchor
point and scale centers.
The notification handling code has been simplified a bit to handle the
increased amount of properties.
Since we override the clean-generic target in order to remove
the shell scripts we create for each conformance test unit, we
cannot use CLEANFILES to remove the test reports.
The maintainer compiler flags we use trigger warnings and errors
in the autogenerated code that gtk-doc creates to scan the header
and source files. Since we cannot control that, and we must run
a distcheck with both --enable-gtk-doc and --enable-maintainer-flags
turned on, we need to use less-strict compiler flags when inside
the doc/reference subdirectories.
The way to do this is to split the maintainer compiler flags into
their own Makefile variable, called MAINTAINER_CFLAGS. The we
can use $(MAINTAINER_CFLAGS) in the INCLUDES or _CFLAGS sections
of each part of the source directories we wish to check with the
anal retentiveness suited for maintainers.
* float-alpha-value:
[script] Parse easing modes by name
[docs] Update the easing modes documentation
[animation] Implement new easing functions
[animation] Move the alpha value to floating point
This better reflects the fact that the api manages sets of vertex attributes,
and the attributes really have no implied form. It is only when you use the
attributes to draw that they become mesh like; when you specify how they should
be interpreted, e.g. as triangle lists or fans etc. This rename frees up the
term "mesh", which can later be applied to a concept slightly more fitting.
E.g. at some point it would be nice to have a higher level abstraction that
sits on top of cogl vertex buffers that adds the concept of faces. (Somthing
like Blender's mesh objects.) There have also been some discussions over
particle engines, and these can be defined in terms of emitter faces; so some
other kind of mesh abstraction might be usefull here.
Okey; to summarise the changes...
We have converted Clutter and Cogl over to using floating point internally
instead of 16.16 fixed, but we have maintained the cogl-fixed API as a
utility to applications in case they want to implement their own optimizations.
The Clutter API has not changed (though ClutterFixed and ClutterUnit are now
internally floats) but all Cogl entry points have been changed to accept floats
now instead of CoglFixed.
To summarise the rationale...
There have been a number of issues with using fixed point though out Clutter
and Cogl including: lack of precision, lack of range, excessive format
conversion (GPUs tend to work nativly with IEEE floats) and maintainability.
One of the main arguments for fixed point - performance - hasn't shown
itself to be serious in practice so far since we seem to be more limited
by GPU performance and making improvements regarding how we submit data to
OpenGL[ES]/the GPU has had a more significant impact.
Ref: The recent multiple rectangle queuing changes + the
cogl-texture-agressive-batching branch which show significant performance
gains, and that recent tests on the ipodtouch (ARM + MBX) also showed no
loss of performance running with floats.
So finally; please forgive the inevitable fallout, this is a far reaching
change. There are still a few known issues with the fixed to float
conversion but enough works for all our conformance tests to pass, and the
remaining issues hopefully wont be too tricky to solve. For reference two
tags will be available either side of this change: "cogl-fixed-end" and
"cogl-float-start"
The easing modes for a ClutterAlpha can either be parsed by using
the enumeration "nickname" (the shorthand form of the enumeration
value) or by using the common naming policy used in other
animation frameworks, like:
easeInCubic
easeOutElastic
easeInOutBounce
Instead of using our own homegrown alpha functions, we should
use the easing functions also shared by other animation frameworks,
like jQuery and Tween, in the interests of code portability.
The easing functions have been defined by Robert Penner and
are divided into three categories:
In Out InOut
Each category has a particular curve:
Quadratic
Cubic
Quartic
Quintic
Sinusoidal
Exponential
Circular
In addition, there are "physical" curves:
Elastic
Back (overshooting cubic)
Bounce (exponentially decaying parabolic)
Finally, the Linear curve is also provided as a reference.
The functions are private, and are meant to be used only
through their logical id as provided by the AnimationMode
enumeration.
The tests should be updated as well to match the new
easing functions.
The current Alpha value is an unsigned integer that can be used
implicitly as a fixed point value. This makes writing an alpha
function overshooting below and above the current range basically
impossible without complicating an already complex code, and
creating weird corner cases.
For this reason, the Alpha value should be defined as a floating
point normalized value, spanning a range between 0.0 and 1.0; in
order to allow overshooting, the valid range is extended one unit
below and one unit above, thus making it -1.0 .. 2.0.
This commit updates the various users of the ClutterAlpha API
and the tests cases.
This commit also removes all the current alpha functions exposed
in the public API.
To deal with all the corner cases that couldn't be scripted a number of patches
were written for the remaining 10% of the effort.
Note: again no API changes were made in Clutter, only in Cogl.
This is the result of running a number of sed and perl scripts over the code to
do 90% of the work in converting from 16.16 fixed to single precision floating
point.
Note: A pristine cogl-fixed.c has been maintained as a standalone utility API
so that applications may still take advantage of fixed point if they
desire for certain optimisations where lower precision may be acceptable.
Note: no API changes were made in Clutter, only in Cogl.
Overview of changes:
- Within clutter/* all usage of the COGL_FIXED_ macros have been changed to use
the CLUTTER_FIXED_ macros.
- Within cogl/* all usage of the COGL_FIXED_ macros have been completly stripped
and expanded into code that works with single precision floats instead.
- Uses of cogl_fixed_* have been replaced with single precision math.h
alternatives.
- Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
angles and math.h replacements.
This simplifies the mucking about with the model-view matrix that was previously
done which improves its efficiency when scaling is necessary.
Notably: There should now be no performance advantage to using
ClutterCloneTexture as a special case clone actor since this method is just as
efficient.
The unit test was renamed to test-actor-clone.
Many use cases for clonning an actor don't require running a shader on the
resulting clone image and so requiring FBOs in these cases is overkill and
in-efficient as it requires kicking and synchronizing a render for each clone.
This approach basically just uses the paint function of another actor to
implement the painting for the clone actor with some fiddling of the model-
view matrix to scale according to the different allocation box sizes of
each of the actors.
A simple unit test called test-actors2 was added for testing.
In order to unify alpha functions and animation modes in ClutterAlpha
we should be able to register alpha functions and get a logical id
for them; the logical id will then be available to be used by
clutter_alpha_set_mode().
The registration requires API changes in ClutterAlpha constructors
and methods. It also provides the chance to shift ClutterAlpha
towards the use of animations modes only, and to alpha functions
as a convenience API for language bindings alone.
Directly calling clutter_actor_paint skips out quite a bit code such as the
backend swap buffer call.
Since we are interested in the highest fps possible, and it now goes through
to the backend swap buffer call we now do a setenv (CLUTTER_VBLANK, none, 0)
before calling clutter_init.
The Effects API and all related symbols have been superceded by
the newly added Animation API and clutter_actor_animate().
This commit removes the Effects implementation, the documentation
and the interactive test/example code.

Instead of including GL/gl.h directly it now includes cogl/cogl.h
instead which should include the right GL header.
Instead of using dlopen to specifically open libGL it now tries to use
dlsym with RTLD_NEXT. This requires defining _GNU_SOURCE on GNU
systems. If RTLD_NEXT is not available it will try passing NULL which
is unlikely to work but it will at least catch the case where it
returns the wrapper version of glGetString to prevent infinite
recursion.
This should hopefully make it work on OS X where the name of the
header and library are different (although this is currently
untested).
* units-rework:
[texture] Do not mix fixed point and units values
[tests] Fix the actor detection
[units] Do not use fixed point and units interchangeably
The API has been changed to take an explicit length for the number of
texture coordinates passed, and it's now documented that if there are
more layers to the current material than the number of texture coords
passed, then default coordinates will be generated for the other
layers.
cogl_material_rectangle should now handle the case where a single
sliced texture is supplied as a material layer by falling back to
cogl_texture_rectangle. We are nearly at the point that
cogl_texture_rectangle could be deprecated. A few issues remain
though, such as not considering waste in cogl_material_rectangle.
My previous work to provide muti-texturing support has been extended into
a CoglMaterial abstraction that adds control over the texture combine
functions (controlling how multiple texture layers are blended together),
the gl blend function (used for blending the final primitive with the
framebuffer), the alpha function (used to discard fragments based on
their alpha channel), describing attributes such as a diffuse, ambient and
specular color (for use with the standard OpenGL lighting model), and
per layer rotations. (utilizing the new CoglMatrix utility API)
For now the only way this abstraction is exposed is via a new
cogl_material_rectangle function, that is similar to cogl_texture_rectangle
but doesn't take a texture handle (the source material is pulled from
the context), and the array of texture coordinates is extended to be able
to supply coordinates for each layer.
Note: this function doesn't support sliced textures; supporting sliced
textures is a non trivial problem, considering the ability to rotate layers.
Note: cogl_material_rectangle, has quite a few workarounds, for a number of
other limitations within Cogl a.t.m.
Note: The GLES1/2 multi-texturing support has yet to be updated to use
the material abstraction.
This follows the convention of GtkLabel/GtkEntry in GTK+ and the old
ClutterEntry.
It makes it easier to use strlen/strcmp etc on the output, since we can
assume that it is always a string.
This commit also updates the test unit for ClutterText to verify that
the clutter_text_get_text() function also returns an empty string when
a ClutterText actor has been created.
When building out of tree the generated scripts for the unit tests
need to explicitly reference the original src dir to be able to find
test-launcher.sh, like this:
$(top_srcdir)/tests/conform/test-launcher.sh
Also test-launcher.sh now passes -m slow --verbose to gtester. Without
-m slow then the wrappers dont work for some of the timeline tests.

A label is now displayed under the rectangle showing the current
gravity. The text for the gravity is taken from the GEnumClass. This
makes it easier to verify that the test is working correctly.
Currently, the conformance test suite creates symbolic links pointing
to a wrapper script that just parses the name used to invoke it and
calls the gtester with the correct path.
Unfortunately, this presents two issues:
- it does not really work on file systems that do not
support symbolic links
- it leaves behind the symbolic links, which cannot
be automatically cleaning by 'make clean'
Both can be solved by creating a small script that invokes the wrapper
one with the test unit path.
The Makefile will use test-conform to extract the unit test paths
and generate a list that will be iterated over to create the
executable name (using the "test-name" convention also used by the
interactive tests, instead of "test_name"); the executable is then
just a simple shell script that invokes the wrapper script passing
the unit test path on the command line. The wrapper script will
use the first argument to work correctly, so it could be simply
executed like:
./test-wrapper.sh /path/to/unit_test
Which is another improvement over the current implementation, where
the wrapper script does not work when invoked directly.
The gdouble value represents an interval along the path from 0.0 to
1.0. This makes more sense than using an alpha value because paths are
not directly related to ClutterAlphas and the rest of the Clutter API
tends to expose gdouble arguments.
The GTest report output allows the developer to know where exactly
a test unit failure happened. The test-text-cache unit makes it
very hard to pinpoint the exact failure location because it relies
on the output to be printed out - which is not the case when the
tests are run as part of a make check.
This commit makes each sub-test inside the unit fail exactly where
the check function fails, which makes it easier to know which sub-test
did actually fail.
Since commit c7c5cf9b ClutterCloneTexture causes an extra paint of the
source actor during the paint run of the cloned texture if the source
is not yet visible. When the stage is first shown it is redrawn
immediatly before it is mapped which means get_paint_visibility will
fail on the source actor so the inner paint will be run. The paint
guards were a global variable so they didn't cope with a second actor
being painted.
The breakage didn't occur until commit d510a4b0 because
get_paint_visibility was also broken.
The nodes of the test path have been reordered because Cairo coalesces
multiple move operations into a single move so the comparison would
fail if the two move nodes are consecutive.
The test-opacity interactive test is superceded by the equivalent
units inside the conformance test suite.
The test-entry interactive test is superceded by the test-text one.
ClutterText behaviour with regards to the paint opacity has been
changed by commit 07e19fff5ffa9617413fa6c3715914513fec3793.
We need to update the test suite for the paint opacity to reflect
that change as well.
The clutter_text_get_chars() function returns a section of the
contents of the Text actor, delimited by a start and an end position.
This commit adds the implementation for that function and a test
unit that guarantees the offset-to-bytes computations are correct.
Comment why we need to enable the editability of the Text actor
inside the test suite.
This should clarify commit ea508ea528d61ae478d8bc4c88f54a89304f18e8
Whenever we are sending specially crafted KeyEvents to a ClutterText
we also need to set it editable, since the event handling code depends
on the editability setting.
Instead of changing the unit for ClutterEntry, we add a new
test unit specifically for ClutterText so that we can later tweak
it specifically for the behaviour changes needed to make ClutterText
work better.
The test-threads interactive test is a good candidate for the
switch from ClutterLabel to ClutterText to verify that the
behaviour of the two classes is the same.
The TidyText actor is meant as a replacement for both ClutterLabel
and ClutterText.
Any text-displaying and editing actor should derive from ClutterText
and implement the various visual cues to differentiate the editable
from the non-editable state. Those visual cues usually belong to
a high-level toolkit, especially if themeing is involved.

key bindings for actors and then execute closures inside the
key-press-event signal handlers, removing the need for big
switch() or if() blocks for each key.

cogl_path_move_to. Previously this always started a new path but
now it instead starts a new disjoint sub path. The path isn't
cleared until you call either cogl_path_stroke, cogl_path_fill or
cogl_path_new. There are also cogl_path_stroke_preserve and
cogl_path_fill_preserve functions.

* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gles/cogl-texture.c: Call cogl_clip_ensure
* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-clip-stack.h: Simplified the clip
stack code quite a bit to make it more maintainable. Previously
whenever you added a new clip it would go through a separate route
to immediately intersect with the current clip and when you
removed it again it would immediately rebuild the entire clip. Now
when you add or remove a clip it doesn't do anything immediately
but just sets a dirty flag instead.
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c: Taken away the code to intersect
stencil clips when there is exactly one stencil bit. It won't work
with path clips and I don't know of any platform that doesn't have
eight or zero stencil bits. It needs at least three bits to
intersect a path with an existing clip. cogl_features_init now
just decides you don't have a stencil buffer at all if you have
less than three bits.
* clutter/cogl/cogl.h.in: New functions and documentation.
* tests/interactive/test-clip.c: Replaced with a different test
that lets you add and remove clips. The three different mouse
buttons add clips in different shapes. This makes it easier to
test multiple levels of clipping.
* tests/interactive/test-cogl-primitives.c: Use
cogl_path_stroke_preserve when using the same path again.
* doc/reference/cogl/cogl-sections.txt: Document the new
functions.

* tests/conform/test-mesh-contiguous.c: Remove the idle source
after the test is complete so that it won't interfere with other
tests.
* tests/tools/Makefile.am: Optionally build the
libdisable-npots.la library depending on whether libdl was
detected in the configure script. A helper script is also
generated to setup the LD_PRELOAD.
* tests/conform/Makefile.am: There are now two versions of the
test-report and full-report rules. test-report-normal is the same
as before and test-report-disable-npots runs the tests with the
disable-npots wrapper script. The full-report rule runs both of
them and displays two separate HTML files. The test-report rule
just runs the normal version as before.
* configure.ac: Add a test for libdl
* tests/tools/disable-npots.sh.in: New file. Template for the
helper script
* tests/tools/disable-npots.c: New file

boxed values when setting the rotation center.
* tests/interactive/test-animation.c:
(on_button_press): Add an example on how to use the rotation
properties to animate an actor.
* tests/interactive/test-pixmap.c (create_pixmap): Use a format
string instead of passing the error message directly to g_error.
* tests/interactive/test-easing.c (test_easing_main)
(on_button_press):
* tests/interactive/test-animation.c (on_button_press): Use
unsigned variables for the results from clutter_actor_get_size
otherwise it complains about the pointer signedness being
different.
* clutter/clutter-script.c (clutter_script_add_search_paths): Use
G_GSIZE_FORMAT instead of %d for a gsize parameter otherwise it
gets upset on 64-bit.

The Mesh API provides a means for submitting an extensible number of
per vertex attributes to OpenGL in a way that doesn't require format
conversions and so that the data can be mapped into the GPU (in vertex
buffer objects) for - hopefully - fast re-use.
There are a number of things we can potentially use this API for, but
right now this just provides a foundation to build on. Please read
the extensive list of TODO items in cogl-mesh.c for examples.
Please refer to the cogl-mesh section in the reference manual for
documentation of the API.

* tests/*:
The tests have been reorganised into different categories: conformance,
interactive and micro benchmarks.
- conformance tests can be run as part of automated tests
- interactive tests are basically all the existing tests
- micro benchmarks focus on a single performance metric
I converted the timeline tests to conformance tests and also added some
tests from Neil Roberts and Ebassi.
Note: currently only the conformance tests use the glib test APIs,
though the micro benchmarks should too.
The other change is to make the unit tests link into monolithic binaries
which makes the build time for unit tests considerably faster. To deal
with the extra complexity this adds to debugging individual tests I
have added some sugar to the makefiles so all the tests can be run
directly via a symlink and when an individual test is run this way,
then a note is printed to the terminal explaining exactly how that test
may be debugged using GDB.
There is a convenience make rule: 'make test-report', that will run all
the conformance tests and hopefully even open the results in your web
browser. It skips some of the slower timeline tests, but you can run
those using 'make full-report'
* clutter/clutter-timeline.c (timeline_timeout_func): Move the
code for firing the new-frame and marker-reached signals into a
separate static function so that it can also be called when the
last frame is reached. Also fix an issue where the frame numbers
were changed in the wrong direction when detecting missed markers
in a reversed timeline. Based on a patch by Michael Boccara.
* tests/test-timeline.c: Now tries to automatically verify whether
the test worked by keeping track of all the signal emissions. The
timelines are run a second time with an extra timeout that causes
delays to simulate skipped frames.

* clutter/cogl/cogl-fixed.h:
* clutter/cogl/cogl.h.in:
* clutter/cogl/common/Makefile.am:
* clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled
after the ClutterFixed. The CoglFixed API supercedes the ClutterFixed
one and avoids the dependency of COGL on Clutter's own API.
* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-primitives.c:

* README: Add release notes.
* clutter/cogl/gles/cogl-fbo.c: Copy the code from gl/cogl-fbo but
use the API calls directly instead of loading an extension because
it is part of the core in GLES 2.
* clutter/cogl/gles/cogl.c (_cogl_features_init): Report
COGL_FEATURE_OFFSCREEN.
* clutter/cogl/gles/cogl-fbo.h (CoglFbo): Add gl_stencil_handle.
* clutter/cogl/gles/cogl-context.h (CoglContext): Add
viewport_store
* tests/test-fbo.c (make_shader): Conditionally use the GLES 2
names of the shader variables
* tests/test-project.c (on_event): Use a return value for the
'event' signal handler, otherwise it might accidentally return
TRUE for unhandled events and you won't be able to close the
window.
* clutter/clutter-stage.c (clutter_stage_read_pixels): Use
OpenGL's coordinate system for the arguments to glReadPixels (so
that y zero is the bottom of the window). Use clutter_redraw
instead of clutter_stage_paint to ensure the right GL context is
selected. Set some of the glPixelStore parameters that might have
been changed by Cogl.
* tests/test-stage-read-pixels.c: Replace with a different test
that gets a sub-region of the stage around the cursor.
* clutter/clutter-main.c (_clutter_id_to_color): When choosing a
pick color, set all but the most significant of the unused
bits. This should make make it more likely that the GL
implementation will round down to the right value.
* tests/test-pick.c: Test case for picking. It creates 192 actors
at known positions and stores their gids. It then calls
clutter_stage_get_actor_at_pos with each position to check that
the right gid is returned.
* tests/Makefile.am (noinst_PROGRAMS): Add test-pick
* clutter/clutter-label.c: Bring back layout caching. This time it
will cache up to three different layouts. The width for which each
layout was generated is stored so that if the same width is
requested again it can use the cached version. If no cached
version is available it will try to replace the oldest
layout. 'Age' is determined by a counter which is incremented
every time a layout is created. The cache is cleared after any
property changes that might affect the layout.
(struct _ClutterLabelPrivate): Removed extents_width,
extents_height and context because they weren't used anywhere.
* tests/test-label-cache.c: Add a test which checks whether the
label is using a different layout when properties are
changed. Also compares the extents of the label's layout with an
independent layout and fails if they aren't the same.
* tests/Makefile.am (noinst_PROGRAMS): Add test-label-cache
Bug 1011 - Fix TFP fallback mechanism (take 2)
* clutter/glx/clutter-glx-texture-pixmap.c:
* tests/test-pixmap.c:
Slightly modified patch from Gwenole Beauchesne applied
to better handle both falling back to non accelerated tfp
and improvements to the test case.
new layout code
* clutter/clutter-texture.c (clutter_texture_new_from_actor): Now
parents the source actor if it doesn't already have a parent so
that it will get an allocation during layout.
* tests/test-fbo.c: One of the tests tries to ensure that the
ClutterTexture clone keeps the source actor alive by derefing
it. However as actors have a floating reference then test-fbo
doesn't have its own reference once the source is parented so
unrefing just steals the parent's reference and causes
badness. The test now claims the floating reference before cloning
the source so that it can safely be unref'd later.
This is now do-what-I-mean like clutter_actor_get_size so that if
the allocation box is available it will use that, otherwise it
will use the preferred size. clutter_actor_transform_vertices has
been converted to clutter_actor_transform_and_project_box so that
it can be used by both functions. Based on a patch by Emmanuele
Bassi.
(clutter_actor_get_abs_allocation_vertices)
(clutter_actor_get_allocation_vertices): These two functions now
force a relayout if the allocation box is not available.
* tests/test-fbo.c: Fixed the shader to use texture2D instead of
texture2DRect now that GL_EXT_texture_rectangle is no longer used.
Add a note to the clutter_stage_read_pixels doc that the alpha channel
isn't guaranteed to contain sensible data

(clutter_texture_get_preferred_height),
(clutter_texture_set_property),
(clutter_texture_get_property),
(clutter_texture_class_init),
(clutter_texture_init): Add the new :keep-aspect-ratio property
to ClutterTexture; when set to TRUE the texture will return a
preferred width maintaining the aspect ratio with the given height
and a preferred height maintaining the aspect ratio with the
given width. This allows to set the width or the height and have
the texture automatically request the height or the width respectively
while maintaining the aspect ratio of the original image.
* tests/test-script.json: Update to test the new :keep-aspect-ratio
property.
* clutter/clutter-actor.c:
(clutter_actor_set_parent): Document and maintain the invariant
that after setting a realized parent on an actor, the actor is
also going to be realized.
(clutter_actor_unparent): Change the invariant that an unparented
actor is also unrealized: the paint is fast enough to avoid
unrealizing, since it also causes more problems that what it's
worth.
* tests/test-invariants.c (test_show_on_set_parent): Update the
invariants test because we changed the invariants.
* clutter/clutter-actor.c (clutter_actor_unparent): Reset the
:show-on-set-parent property to TRUE when unparenting.
* tests/Makefile.am: Add test-invariant to the build.
* tests/test-invariants.c: Test the invariants that we are going
to honour (and document, at some point).
* tests/test-layout.c: Take into account the origin of the
parent, if it has changed, and queue a relayout if we are
using the transformed box when computing the layout.
Bug #815 - Split up request, allocation, and paint box
* clutter/clutter-actor.[ch]: Rework the size allocation,
request and paint area. Now ::request_coords() is called
::allocate(), and ::query_coords() has been split into
::get_preferred_width() and ::get_preferred_height(). See
the documentation and the layout test on how to implement
a container and layout manager with the new API. (#915,
based on a patch by Havoc Pennington, Lucas Rocha and Johan
Bilien)
* clutter/clutter-clone-texture.c: Port CloneTexture to
the new size negotiation API; it just means forwarding
the requests to the parent texture.
* clutter/clutter-deprecated.h: Add deprecated and replaced
API.
* clutter/clutter-entry.c: Port Entry to the new size
negotiation API.
* clutter/clutter-group.c: Port Group to the new size
negotiation API; the semantics of the Group actor do not
change.
* clutter/clutter-label.c: Port Label to the new size
negotiation API, and vastly simplify the code.
* clutter/clutter-main.[ch]: Add API for executing a
relayout when needed.
* clutter/clutter-private.h: Add new Stage private API.
* clutter/clutter-rectangle.c: Update the get_abs_opacity()
call to get_paint_opacity().
* clutter/clutter-stage.c:
(clutter_stage_get_preferred_width),
(clutter_stage_get_preferred_height),
(clutter_stage_allocate),
(clutter_stage_class_init): Port Stage to the new size
negotiation API.
* clutter/clutter-texture.c: Port Texture to the new size
negotiation API.
* clutter/clutter-types.h: Add ClutterRequestMode enumeration.
* clutter/x11/clutter-stage-x11.c: Port the X11 stage
implementation to the new size negotiation API.
* tests/Makefile.am: Add the layout manager test case.
* tests/test-opacity.c: Update.
* tests/test-project.c: Update.
* tests/test-layout.c: Test case for a layout manager implemented

Bug#959 - Multiple minor improvements
* configure.ac: pick up GDKPIXBUF_PREFIX from gdk-pixbuf-2.0
module, not pango
* clutter/clutter-keysyms-table.h: cosmetic fix for ifdef guard
name in the comment (leftover from earlier commit)
* tests/test-textures.c: don't depend on GdkPixbuf as we're not
using any actual features from it, just plain pixel buffer
manipulation
* clutter/clutter-timeline.c
* clutter/clutter-timeline.h (clutter_timeline_list_markers): Use
gsize* to return number of items, not guint*
* tests/test-paint-wrapper.c: use correct type (guint*) in call
to clutter_actor_get_size()
* tests/test-depth.c (janus_group): properly take height2 into
account when calculating needed height for the rectangle
* tests/test-cogl-tex-getset.c: use rowstride, not width*4, when
calculating pixel offsets
* tests/test-cogl-tex-getset.c: Don't assume/force RGBA format,
also support ARGB format (needed with quartz imageloader.)
control the use of mipmapping.
* clutter/clutter-texture.h: added ClutterTextureQuality enum.
* tests/test-texture-quality.c: new test.
* tests/Makefile.am: added test-texture-quality
* clutter/clutter-texture.c:
(clutter_texture_class_init): Do not unrealize on hide(), and
do not realize() on show. By default, clutter_actor_show() will
realize ourselves, and we don't want to unrealize when hidden
to avoid paying the penalty of reading back the texture data
from the video memory.
* tests/test-actors.c: Show all textures again when pressing
the 'r' key.
sampler2DRect now that GL_TEXTURE_RECTANGLE support is disabled in
revision 2834. The ClutterTexture actor now has the
'disable-slicing' property set. The distance in texture
coordinates between pixels is passed in as a uniform so that the
box-blur shader can still work.
* tests/Makefile.am:
* tests/test-paint-wrapper.c: Add a test case (merely, a copy
of test-actors.c) that verifies that handlers to the ::paint
signal are called in the right order.
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gl/cogl.c: The clip planes are now set using the
inverse projection matrix as the modelview matrix so that they can
be specified in screen coordinates.
* clutter/cogl/gles/cogl-context.h (CoglContext):
* clutter/cogl/gl/cogl-context.h (CoglContext): Added a member to
cache the inverse projection matrix
* clutter/clutter-fixed.h: Added a constant for converting from
radians to degrees.
* clutter/clutter-fixed.c (clutter_atani, clutter_atan2i): Added
fixed-point versions of atan and atan2.
* tests/test-clip.c: Added a test for clipping with various
rotations and depths.

* clutter/clutter-model.h: Fix documentation.
* clutter/eglnative/clutter-backend-egl.[ch]:
* clutter/eglnative/clutter-event-egl.c: Add the same solution
used for the SDL backend in order to get the time of an event.
This should fix the motion event throttling and the click count
on button press.
* tests/test-pixmap.c (create_pixmap), (main): Fix preprocessor
directives.
* tests/test-events.c: Clean up a bit, and print out more
messages when pressing one of the rectangles.
* tests/test-threads.c: Be more verbose in the console, and
apply another behaviour on the rectangle, to show that we
are not blocking.
* clutter/x11/clutter-x11-texture-pixmap.c:
* configure.ac:
* tests/Makefile.am:
Remove the XComposite dep from Clutter itself, just use
in test-pixmap (if available)
Rework the stage wrapper/implementation relation: remove
duplicated code and all the bookkeeping from the backends into
ClutterStage whenever possible, to reduce the amount of work a
backend must do (and possibly get wrong). Thanks to Tommi
Komulainen.
* clutter/clutter-main.c:
(clutter_init_with_args), (clutter_init): Realize the default
stage after creation. The default stage is special, because we
use it in the initialization sequence. This removes the burden
from the backends and reduces the things a backend can get
wrong.
* clutter/clutter-stage.c:
(clutter_stage_show): Make sure to realize the implementation if
it hasn't been realized yet.
(clutter_stage_realize): Set the REALIZED flag and call
clutter_stage_ensure_current() if the implementation was
successfully realized.
(clutter_stage_unrealized): Call clutter_stage_ensure_current()
on unrealize.
* clutter/glx/clutter-backend-glx.c:
(clutter_backend_glx_create_stage): Do not realize the stage anymore
when creating it, and let the normal realization sequence take
place.
(clutter_backend_glx_ensure_context): Trap for X11 errors.
* clutter/glx/clutter-stage-glx.c:
(clutter_stage_glx_realize): Chain up to the X11 implementation
so that we can set up the window state (title, cursor visibility)
when we actually have a X window. Also, do not call
clutter_stage_ensure_current(), and rely on the wrapper to do
it for us. This means we can drop setting the REALIZED flag on
the wrapper.
(clutter_stage_glx_unrealize): Do not call
clutter_stage_ensure_current() ourselves, and rely on the wrapper
to do it for us.
* clutter/x11/clutter-stage-x11.c:
(set_wm_title), (set_cursor_visible): Move the WM title and
cursor visibility code inside their own functions.
(clutter_stage_x11_realize): Set the window title and whether the
cursor is visible or not after realizing the stage.
(clutter_stage_x11_set_cursor_visible),
(clutter_stage_x11_set_title): Call set_wm_title() and
set_cursor_visible().
(clutter_stage_x11_finalize): Free the title string.
* clutter/x11/clutter-stage-x11.h: Save more of the stage state,
so that we can set it even when the stage hasn't been realized
yet.
* clutter/eglnative/clutter-backend-egl.c:
(clutter_backend_egl_create_stage):
* clutter/eglnative/clutter-stage-egl.c:
(clutter_stage_egl_unrealize),
(clutter_stage_egl_realize): Update the eglnative backend.
* clutter/eglx/clutter-backend-egl.c:
(clutter_backend_egl_ensure_context),
(clutter_backend_egl_create_stage):
* clutter/eglx/clutter-stage-egl.c:

* clutter/sdl/clutter-backend-sdl.c:
(clutter_backend_sdl_create_stage):
* clutter/sdl/clutter-stage-sdl.c:
(clutter_stage_sdl_realize): Update the sdl backend.
* clutter/fruity/clutter-backend-fruity.c:
(clutter_backend_fruity_create_stage):
* clutter/sdl/clutter-stage-fruity.c:
(clutter_stage_fruity_realize): Update the fruity backend.
* tests/test-multistage.c (on_button_press): Bail out if
clutter_stage_new() returns NULL.
* HACKING.backends: Update backend writing documentation.
* clutter/clutter-script-private.h: Add a flag for the
default stage.
* clutter/clutter-script.c:
(json_object_end): If the "type" member is "ClutterStage"
and we have a "is-default" member set to true then this
is the default stage.
(clutter_script_construct_object): Special case the default
stage instead of each ClutterStage.
(object_info_free): Ditto as above.
* tests/test-script.json: Test the creation of a non-default
stage and the ::destroy handler to quit.
Bug #902 - Support transform from G_TYPE_INT to ClutterUnit
* clutter/clutter-units.c:
(clutter_value_transform_int_unit),
(clutter_unit_get_type): Add GValue transformation function from
integer values to ClutterUnit. (#902)
(param_unit_validate): Fix validation for ClutterParamSpecUnit;
this allows writable ClutterUnit properties.
* clutter/clutter-fixed.c:
(clutter_value_transform_int_fixed),
(clutter_value_transform_double_fixed),
(clutter_value_transform_float_fixed): Add GValue transformation
functions from native types (int, double, float) to ClutterFixed.
(clutter_fixed_get_type): Register the new transformation functions.
(param_fixed_validate): Fix validation for ClutterParamSpecUnit;
this allows writable ClutterFixed properties.
* clutter/cogl/gl(es)/cogl-texture.h:
* clutter/cogl/gl(es)/cogl-texture.c:
cogl_texture_new_* functions take a gboolean auto_mipmap argument.
If TRUE automatic mipmap generation is enabled during the process
of slice texture object creation.
(cogl_texture_new_from_foreign:) now allows mipmap min filter
flags.

* tests/test-cogl-tex-polygon.c:
* tests/test-cogl-tex-getset.c:
Pass FALSE for auto_mipmap to cogl_texture_new_*.
* clutter/pango/pangoclutter-render.c:
(tc_get:) Pass TRUE to cogl_texture_new_with_size and use mipmap
min filter for nicer glyphs at small scales. As a result test-text
has gone all beautiful now.
* clutter/cogl/common/cogl-primitives.c: api review touch ups.
* clutter/cogl/gl/cogl-primitives.c: (cogl_path_fill),
(cogl_path_stroke): indentation.
* clutter/cogl/gles/cogl-primitives.c:
(_cogl_path_fill_nodes): free allocated resources.
* tests/test-cogl-primitives.c: updated to new API, added rotation to
test to show that cogl renders paths correct under perspective
distortion.
* clutter/glx/clutter-glx-texture-pixmap.c:
* tests/test-pixmap.c:
Fix up texture-pixmap, now works.
Thanks to Neil for spotting we were actually using
wrong texture type in fbconfig (COGL change).
primitives and path API a bit smaller and more resembling cairo.

* clutter/glx/clutter-backend-glx.h:
* clutter/x11/clutter-x11-texture-pixmap.c:
* clutter/x11/clutter-x11-texture-pixmap.h:
General cleanup of texture pixmap code, adding;
- Pixmap dimentions and depth now auto probed, read only props.
- More X safety traps
- Add support for optionally tracking damage and automatically
updating texture.
* clutter/glx/clutter-glx-texture-pixmap.c:
* clutter/glx/clutter-glx-texture-pixmap.h:
General cleanup and some safety additions. Needs more work so
'proper' subclass - dependent on new COGL.
* clutter/x11/clutter-backend-x11.c: (clutter_x11_remove_filter):
Invert g_return_if check.
* configure.ac:
Pull in XComposite and XDamage (at least for now)
* tests/Makefile.am:
* tests/test-pixmap.c:
Add a modified test from Johan for above.
* README: Add a note about the Shader API changes.
* clutter/clutter-deprecated.h: Add deprecation symbols.
* clutter/clutter-shader.[ch]: Rename the :bound read-only
property to :compiled. Also rename clutter_shader_bind()
and clutter_shader_is_bound() to clutter_shader_compil() and
clutter_shader_is_compiled(), respectively.
* clutter/glx/clutter-stage-glx.c:
(clutter_stage_glx_unrealize): Update after
clutter_shader_release_all() rename.
* tests/test-shader.c (button_release_cb), (main): Update.
Bug #864 - Allow instantiating and subclassing of ClutterStage
* clutter/Makefile.am: Add clutter-stage-window.[ch]
* clutter/clutter-stage-manager.c:
(_clutter_stage_manager_remove_stage): Do not warn if removing
a stage we don't manage, as we might be invoked multiple times
during a ClutterState dispose sequence.
* clutter/clutter-actor.c:
* clutter/clutter-backend.[ch]:
* clutter/clutter-main.c:
* clutter/clutter-private.h:
* clutter/clutter-stage.[ch]: Make ClutterStage a proxy actor,
with a private actor implementing the ClutterStageWindow
interface for handling the per-backend realization, painting
and unrealization, plus all the windowing system abstraction.
* clutter/x11/clutter-event-x11.c:
* clutter/x11/clutter-stage-x11.[ch]: Port the X11 backend
to the new backend and stage API and semantics.
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-stage-glx.c: Port the GLX backend to
the new backend and stage API and semantics.
* clutter/eglx/clutter-backend-egl.[ch]:
* clutter/eglx/clutter-stage-egl.[ch]: Port the EGLX backend
to the new backend and stage API and semantics (untested).
* tests/test-multistage.c (on_button_press): Rename
clutter_stage_create_new() to clutter_stage_new().
* clutter/clutter-actor.c:
Remove uneeded stage private member.
Add show-on-set-parent prop and make so by default Actors are
now automatically shown when reparented (#791)
* clutter/eglx/clutter-backend-egl.c:
* clutter/cogl/gles/cogl.c:
A couple of minor comments.
* clutter/eglnative/Makefile.am:
Add missing clutter-egl.h header (back port from trunk)
* tests/test-actors.c:
Modify to take advantage of new show-on-set-parent functionality.
* clutter/clutter-score.[ch]: Remove all the API changes, and
just add a clutter_score_append_at_marker(); the implementation
remains the same, but the marker must be explicitly created by
the developer. The ids are no longer used to create implicit
markers, so they can return to be unsigned integers.
* clutter/clutter-timeline.[ch]:
(clutter_timeline_has_marker): Add a function to query a timeline
for a marker being set.
* tests/test-score.c (main): Update with the API changes.
* clutter.symbols: Update exported symbols.
* clutter.symbols: Add new symbols
* clutter/clutter-score.[ch]: Use the newly added marker API
on the timelines to implement attaching timelines at specific
points, using either milliseconds or frames.
* tests/test-score.c (main): Test the new API.
* clutter/clutter-marshal.list: Add signature for the
::marker-reached signal marshaller.
* clutter/clutter-timeline.[ch]: Add timeline marker API;
using markers it is possible to add a unique identifier to
a particular frame of the timeline, and receive a signal
notification when reaching that particular marker while
playing the timeline. (#641)
* tests/test-timeline.c: Update the test case to check for
the marker-reached signal emission.
* clutter.symbols: Add new symbols.
