To convert from a TextureQuality to a COGL filter enumeration
we need to perform two function calls. Since we need both filters
when calling cogl_texture_set_filters() we can safely consolidate
the two conversion functions into one. This also allows using a
shorter function name, thus reducing the lenght of the lines
involved and, more importantly preventing Emmanuele from crying.
Otherwise if the dipose method is called twice the material will
already be destroyed when texture_free_gl_resources is called so it
will issue a warning about an invalid handle.
The 'no_slice' property means the texture should never be sliced. We
want cogl to create a texture with any amount of waste so we pass
max_waste as -1. However this got broken in commit 168d55 so that the
meaning got negated (no_slice enabled slicing).
When setting the cogl texture, the ClutterTexture takes a reference to
the Cogl handle but the material takes an additional reference when it
is set as the layer. Nothing was unrefing the temporary reference so
the textures were being leaked.

cogl_set_source_color4ub was previously used to set a transparent
white source color according to the actors opacity, but since
cogl_set_source_color now always implies you want a solid fill we
we use cogl_material_set_color4ub to achieve the same result.
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.
If a ClutterTexture does not sync size, it should be possible to
change the texture size without causing a relayout.

Boolean arguments for functions are pretty evil and usually
lead to combinatorial explosion of parameters in case multiple
settings are added.
In the case of the COGL texture constructors we have a boolean
argument for enabling the auto-mipmapping; it is conceivable that
we might want to add more settings for a COGL texture without
breaking API or ABI compatibility, so the boolean argument should
become a bitmask.
The internals have not been changed: instead of checking for
a non-zero value, we check for a bitmask being set.
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"
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.
It's more sensible to use 2^n-1 for a max tile-waste value rather
than 2^n, so change the value default from 64 to 63. Example:
191 and 192 will both be sliced to 128+64 rather than having
191=>128+64, 192=>256.

The ::load-finished signal is emitted only when loading a texture
using clutter_texture_set_from_file(). Since this breaks user
expectations and consistency, we should also emit ::load-finished
when loading a texture from image data.
The size of the texture as retrieved by the filename should
be set as the image size, not as the actor size, in order to
respect the :sync-size property.
When the asynchronous loading process terminates, we queue
a relayout so that the scene is updated.
Provide a main loop-based fallback to the asynchronous loading in
case the GLib threading support hasn't been enabled. This also
allows us to clean up the asynchronous loading machinery and have
it behave consistently across different scenarios.
Emit the ::load-finished even if the asynchronous loading from
disk was not enabled.
Finally, block clutter_texture_set_from_file() until we have an
image width and height, so that querying the texture actor size
after set_from_file() will still yield the correct result even
when asynchronous loading is set.
* 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.
This converts clutter-texture to use the new CoglMaterial API instead of
cogl_texture_rectangle.
This change does not add multi-texturing support to Clutter, it's more about
aiming to deprecate cogl_texture_rectangle, and moving everything over to the
cogl_set_source(material); cogl_draw_somthing(); coding pattern.
With this patch, the code can be built with/without CoglMaterial support so we
can do comparisons of the old/new code for a transient period. (look for the
USE_COGL_MATERIAL define)
Note: The FBO paths haven't currently been tested, so they may need some
tweaks.

parents the source actor if it doesn't already have a parent so
that it will get an allocation during layout.

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.

search paths inside ClutterScript and to look up a specific filename
inside those search paths. This is useful to define a set of

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.

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

* clutter/clutter-actor.c:
(clutter_actor_real_request_coords),
(clutter_actor_request_coords),
(clutter_actor_class_init): Provide a default ::request_coords()
implementation in ClutterActor and use it to store the bounding
box passed to clutter_actor_request_coords(). This makes the code
more reliable and clean, and avoids a call to the subclass
request_coords() method if the bounding box did not change. Now,
every class overriding ClutterActor::request_coords() *must* chain
up to the parent class method or the bounding box will not be
saved inside the ClutterActor structure.

Use take_object when getting pixbuf prop to avoid ref leak
Most of these fixes are simple symbol shadowing issues, like index and the
braindead y0 and y1 extern symbols exported by math.h on GNU libc systems.
There is a masking issue in ClutterTexture which should be checked; I ran
the tests and everything looked fine.
The rest are just unused variables.

Add initial 'cogl' implementation. 'cogl' is a simple abstration
layer over GL and GL/ES used by clutter internally. It should
eventually allow clutter applications to be run on both GL and GL/ES
with just a recompile as well as provide more debugging and potentially
profiling information for GL and GL/ES usage.
This commit contains the initial GL implementation.
Revert to copying GdkPixbuf areas to correctly implement the texture
tiling. This fixes segmentation faults occurring with cards with a
small texture memory area.

* clutter/clutter-private.h: Remove inclusion of backend-specific
headers; update the main context object; add the declarations for
the event queue functions.
* clutter/clutter-backend.[ch]: Add the abstract ClutterBackend
object, which holds backend-specific settings, the main stage,
and the event queue. Every backend must implement a subclass of
ClutterBackend and ClutterStage.

move out the keysym-to-unicode table; add the new event types.
* clutter/clutter-color.h: Include clutter-fixed.h
* clutter/clutter-main.c: Update API; get the main stage
from the backend object; process the event received from the
queue; lock/unlock the main mutex if we have one; move the
initialisation process sooner in the init sequence, in order to
have the backend object when we check for options; call the
backed vfuncs in the pre/post parse hooks.

Backport of fix to get_pixbuf on non alpha textures from 0_2 branch.
Rework part of the show/hide machinery. Allow groups sub-classes
and composite actors to override show_all/hide_all in order to
decide which children they wish to show/hide. This means that
if an actor overrides the default show/hide virtual methods, it'll
have to chain up to the parent class show/hide. While we're at it,
provide the fully recursive clutter_actor_show_all() and
clutter_actor_hide_all() methods.
* clutter/clutter-behaviour-path.c: Add apidoc for the ClutterKnot
functions; add pathological equality case for clutter_knot_equal().

* clutter/clutter-event.c: Add apidoc
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a clutter_actor_show_all() and a
clutter_actor_hide_all() functions; provide a mechanism for
groups and composited actors to programmatically select what to
show/hide when clutter_actor_show_all() and clutter_actor_hide_all()
are called. If you are overriding the ClutterActor::show or
the ClutterActor::hide virtual methods you should chain up with
the parent class.
* clutter/clutter-group.c: Override show_all and hide_all and
recursively show/hide every child inside the group;
clutter_group_show_all() and clutter_group_hide_all() remain as non
recursive versions of clutter_actor_show_all() and
clutter_actor_hide_all() (maybe we should rename them in order
to avoid name clashes with the bindings).
* clutter/clutter-stage.c:
* clutter/clutter-texture.c: Chain up with parent class show
and hide vfuncs.
* clutter/clutter-clone-texture.h:
* clutter/clutter-clone-texture.c: Provide API for changing the
parent texture of a clone texture actor.
* examples/behave.c:
* examples/super-oh.c:
* examples/test.c: Use clutter_actor_show_all() instead of
clutter_group_show_all().
* clutter/clutter-private.h: Add our own READABLE,
WRITABLE and READWRITE paramspec flags, declaring the
string components of the properties GParamSpec as static;
this should shave off some bytes in the memory footprint
and avoid relocations.

macros we just added.
* clutter/clutter-behaviour-scale.c: Add properties for
the scale begin, scale end and gravity parameters.
* clutter/clutter-behaviour-path.h: Mark the ClutterKnot
memory management functions as public (for the bindings),
since we use the slice allocator for copying knots around;
add a clutter_knot_equal() function.
* clutter/clutter-behaviour-path.c:
(node_distance): Use clutter_knot_equal() as a fast path
to avoid the sqrt() in case the nodes we are using are
at the same position.
(path_total_length): Additional check on the existence
of the next node.
* examples/behave.c: Do not leak the ClutterBehaviour
objects around.
* clutter/clutter-texture.h: Clean up.
* clutter/clutter-texture.c: Typo fix in the name
of ClutterTextureTileDimension.

in the finalize process).

* clutter/clutter-debug.h:
Make CLUTTER_NOTE() just take a string rather than a func.
Add more default context to output.
* configure.ac:
Fix flag and add more help docs for --ebable-debug option.
* configure.ac: Enable debug messages also when
--enable-debug is set to "minimum".
* clutter/Makefile.am:
* clutter/clutter-debug.h: Move all debugging macros inside
this private header; make all debug macros depend on the
CLUTTER_ENABLE_DEBUG compile time define, controlled by
the --enable-debug configure switch; add G_LOG_DOMAIN define.
* clutter/clutter-main.c: Clean up the debug stuff; add
command line argument parsing using GOption; the debug
messages now are triggered like this:
CLUTTER_DEBUG=section:section:... clutter-app
or like this:
clutter-app --clutter-debug=section:section:...
where "section" is one of the sections listed in clutter-main.c,
or "all", for all sections; each section is bound to a flag,
which can be used to define a domain when adding a debug note
using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
CLUTTER_NOTE() is used like this:
CLUTTER_NOTE (DOMAIN, log-function);
where log function is g_printerr(), g_message(), g_warning(),
g_critical() or directly g_log() - for instance:
CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));
will print the warning only if the "pango" flag has been
set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
command line argument.
similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
command line switch; also, the --display and --screen command
line switches have been added: the first overrides the DISPLAY
envvar and the second controls the X screen used by Clutter to
get the root window on the display.
* clutter/clutter-main.h:
* clutter/clutter-main.c: Add extended support for GOption
in Clutter; use clutter_init_with_args() to let Clutter
parse your own command line arguments; use instead
clutter_get_option_group() to get the GOptionGroup used by
Clutter if you want to do the parsing yourself with
g_option_context_parse(). The init sequence has been verified,
updated and moved into common functions where possible.
* clutter/pango/pangoclutter-render.c:
* clutter/*.c: Include "clutter-debug.h" where needed; use
CLUTTER_NOTE() instead of CLUTTER_DBG().
* examples/super-oh.c: Use the new clutter_init_with_args()
function, and add a --num-hands command line switch to
the SuperOH example code controlling the number of hands at
runtime.
