ec59af290c analysis: None used in pointer context
While this is totally fine (None is 0L and, in the pointer context, will
be converted in the right internal NULL representation, which could be a
value with some bits to 1), I believe it's clearer to use NULL instead
of None when we talk about pointers.

589c8d9579 [texture] Support picking textures according to their alpha channel
This adds a boolean "pick-with-alpha" property to ClutterTexture and when
true, it will use the textures alpha channel to define the actors shape when
picking.

Users should be aware that it's a bit more expensive to pick textures like
this (so probably best not to blindly enable it on *all* your textures)
since it implies rasterizing the texture during picking whereas we would
otherwise just send a solid filled quad to the GPU.  It will also interrupt
the internal batching of geometry for pick renders which can otherwise often
be done in a single draw call.

728e2d8071 drag: Add a default drag-motion behaviour
The DragAction should, by default, drag the actor to which it has been
applied, instead of delegating what to do to the developer. If custom
code need to override it, g_signal_stop_emission_by_name() can be called
to stop the default handler to ever running.

ff7ce2c5b2 test-cogl-materials: Run the 'all layers' test with different prims
The drawing code from test_invalid_texture_layers which draws a
rectangle, a polygon and a vertex buffer has been split out to
separate function. test_using_all_layers now also uses this so that it
will also test the other two primitives. This causes the test to fail
when all of the layers are drawn using a vertex buffer.

4fd74e71e6 action: Add DragAction, an action implementing drag capabilities
DragAction is an Action sub-class that provides dragging capabilities to
any actor. DragAction has:

  • drag-begin, drag-motion and drag-end signals, relaying the event
    information like coordinates, button and modifiers to user code;

  • drag-threshold property, for delaying the drag start by a given
    amount of pixels;

  • drag-handle property, to allow using other actors as the drag
    handle.

  • drag-axis property, to allow constraining the dragging to a specific
    axis.

An interactive test demonstrating the various features is also provided.

21117bb7a9 test-conform-common: Disconnect all paint handlers on the stage
A few of the tests connected to the paint signal but never
disconnected it. Most of these handlers had a call to g_main_quit in
them which meant that it could sometimes cause subsequent tests to
exit after the first frame is painted. Most of the tests don't
validate any of the results until after a couple of frames have been
rendered so this ended up skipping out the test entirely.

To workaround this the test setup function now disconnects all
handlers for the paint signal on the default stage before the test is
run.

a3bc4a6009 test-cogl-materials: Add a test using the maximum number of layers
This adds a test which creates a material using the maximum number of
layers. All of the layers are assigned a white texture except the last
which is set to red. The default combine mode is used for all of the
layers so the final fragment should end up red.

Currently Cogl doesn't provide a way to query the maximum number of
layers so it just uses glGetIntegerv instead. This might cause
problems on GLES 2 because that adds additional restrictions on the
number of layers.

fddd316986 test-cogl-path: Test sub paths and intersections
This changes the original tests so that it splits the original path
into two sub paths. When adding a new block to the copied path it also
adds another sub path. This further stresses the path copying
mechanism and exposes a bug.

It also tests intersections by drawing a self-intersecting path and a
path with two sub-paths that overlap. Where the path overlaps it
should be inverted.

test-cogl-tex-polygon creates a separate material so that it can set

paint functions assume the correct source is set up instead of trying

7b63da69cf Add "homogeneous" mode to ClutterBoxLayout.
Added new "homogeneous" mode to ClutterBoxLayout, that makes layout children
get all the same size.

This is heavily inspired in the "homogeneous" attribute available in GtkBox,
but simplified as we don't have padding nor borders in box layout, only
spacing.

Also added to test-box-layout a key to set/unset homogeneous mode.

* Coding style fixes.
* Added proper test for homogeneous mode in box layout.
* Fix in homogeneous mode.

c0a553163b cogl: Support any format in cogl_read_pixels
cogl_read_pixels() no longer asserts that the format passed in is
RGBA_8888 but instead accepts any format. The appropriate GL enums for
the format are passed to glReadPixels so OpenGL should be perform a
conversion if neccessary.

It currently assumes glReadPixels will always give us premultiplied
data. This will usually be correct because the result of the default
blending operations for Cogl ends up with premultiplied data in the
framebuffer. However it is possible for the framebuffer to be in
whatever format depending on what CoglMaterial is used to render to
it. Eventually we may want to add a way for an application to inform
Cogl that the framebuffer is not premultiplied in case it is being
used for some special purpose.

If the requested format is not premultiplied then Cogl will convert
it. The tests have been changed to read the data as premultiplied so
that they won't be affected by the conversion. Picking in Clutter has
been changed to use COGL_PIXEL_FORMAT_RGB_888 because it doesn't need
the alpha component. clutter_stage_read_pixels is left unchanged
because the application can't specify a format for that so it seems to
make most sense to store unpremultiplied values.

0d428655e2 actor: Turn push/pop_internal into Actor methods
Since the "internal" state is global, it will leak onto actors that you
didn't intend for it to, because it applies not just to the actors you
create, but also to any actors *they* create. Eg, if you have a dialog
box class, you might push/pop_internal around creating its buttons, so
that those buttons get marked as internal to the dialog box. But
ctx->internal_child will still be set during the *button*'s constructor
as well, and so, eg, the label and icon inside the button actor will
*also* be marked as internal children, even if that isn't what the
button class wanted.

The least intrusive change at this point is to make push_internal() and
pop_internal() two methods of the Actor class, and take a ClutterActor
pointer as the argument - thus moving the locality of the internal_child
counter to the Actor itself.

given that the getter function returns guint8 values so this also adds a

ClutterAnimator is a class for managing the animation of multiple
properties of multiple actors over time with keyframing of values.

The Animator class is meant to be used to effectively describe
animations using the ClutterScript definition format, and to construct
complex implicit animations from the ground up.

830f2402d4 Merge branch 'more-texture-backends'
This adds three new texture backends.

- CoglTexture2D: This is a trimmed down version of CoglTexture2DSliced
  which only supports a single texture and only works with the
  GL_TEXTURE_2D target. The code is a lot simpler so it has a less
  overheads than dealing with slices. Cogl will use this wherever
  possible.

- CoglSubTexture: This is used to get a CoglHandle to represent a
  subregion of another texture. The texture can be used as if it was a
  standalone texture but it does not need to copy the resources.

- CoglAtlasTexture: This collects RGB and RGBA textures into a single
  GL texture with the aim of reducing texture state changes and
  increasing batching. The backend will try to manage the atlas and
  may move the textures around to close gaps in the texture. By
  default all textures will be placed in the atlas.

de31cbf4f7 test-cogl-multitexture: use several materials with texture matrices
A small doubt has risen about the use of CoglTextureUnit in materials:
will texture matrices still work if we have several materials, each of
them having at texture on the same texture unit? The answer is yes!

test-cogl-multitexture has been extended to use 2 materials with about
the same setup except a little difference: the texture matrices for the
lightmaps rotate in opposite directions.

While at it, changed the rotation behaviour by an implicit animation
with a small additional bonus bling.

36f18e5ac5 cogl: Make CoglSubTexture only work for quad rendering
The sub texture backend doesn't work well as a completely general
texture backend because for example when rendering with cogl_polygon
it needs to be able to tranform arbitrary texture coordinates without
reference to the other coordintes. This can't be done when the texture
coordinates are a multiple of one because sometimes the coordinate
should represent the left or top edge and sometimes it should
represent the bottom or top edge. For example if the s coordinates are
0 and 1 then 1 represents the right edge but if they are 1 and 2 then
1 represents the left edge.

Instead the sub-textures are now documented not to support coordinates
outside the range [0,1]. The coordinates for the sub-region are now
represented as integers as this helps avoid rounding issues. The
region can no longer be a super-region of the texture as this
simplifies the code quite a lot.

There are two new texture virtual functions:

transform_quad_coords_to_gl - This transforms two pairs of coordinates
     representing a quad. It will return FALSE if the coordinates can
     not be transformed. The sub texture backend uses this to detect
     coordinates that require repeating which causes cogl-primitives
     to use manual repeating.

ensure_non_quad_rendering - This is used in cogl_polygon and
     cogl_vertex_buffer to inform the texture backend that
     transform_quad_to_gl is going to be used. The atlas backend
     migrates the texture out of the atlas when it hits this.

2e6397c391 box-layout: Add knobs for controlling animations
ClutterLayoutManager does not have any state associated with it, and
defers all the state to its sub-classes.

The BoxLayout is thus in charge of controlling:

  • whether or not animations should be used
  • the duration of the animation
  • the easing mode of the animation

By adding three new properties:

  • ClutterBoxLayout:use-animations
  • ClutterBoxLayout:easing-duration
  • ClutterBoxLayout:easing-mode

And their relative accessors pairs we can make BoxLayout decide whether
or not, and with which parameters, call the begin_animation() method of
ClutterLayoutManager.

The test-box-layout has been modified to reflect this new functionality,
by checking the key-press event for the 'a' key symbol to toggle the use
of animations.

439f8c62b0 cogl: deprecate cogl_draw_buffer API and replace with a cogl_framebuffer API
cogl_push_draw_buffer, cogl_set_draw_buffer and cogl_pop_draw_buffer are now
deprecated and new code should use the new cogl_framebuffer_* API instead.

Code that previously did:
    cogl_push_draw_buffer ();
    cogl_set_draw_buffer (COGL_OFFSCREEN_BUFFER, buffer);
    /* draw */
    cogl_pop_draw_buffer ();
should now be re-written as:
    cogl_push_framebuffer (buffer);
    /* draw */
    cogl_pop_framebuffer ();

As can be seen from the example above the rename has been used as an
opportunity to remove the redundant target argument from
cogl_set_draw_buffer; it now only takes one call to redirect to an offscreen
buffer, and finally the term framebuffer may be a bit more familiar to
anyone coming from an OpenGL background.

272e227109 [cogl-clip] deprecate parts and cleanup the API
cogl_clip_push() which accepts a rectangle in model space shouldn't have
been defined to take x,y,width,height arguments because this isn't consistant
with other Cogl API dealing with model space rectangles.  If you are using a
coordinate system with the origin at the center and the y+ extending up,
then x,y,width,height isn't as natural as (x0,y0)(x1,y1). This API has
now been replace with cogl_clip_push_rectangle()

(As a general note: the Cogl API should only use the x,y,width,height style
when the appropriate coordinate space is defined by Cogl to have a top left
origin.  E.g.  window coordinates, or potentially texture coordinates)

cogl_clip_push_window_rect() shouldn't have been defined to take float
arguments since we only clip with integral pixel precision. We also
shouldn't have abbreviated "rectangle". This API has been replaced with
cogl_clip_push_window_rectangle()

cogl_clip_ensure() wasn't documented at all in Clutter 1.0 and probably
no one even knew it existed. This API isn't useful, and so it's now
deprecated. If no one complains we may remove the API altogether for
Clutter 1.2.

cogl_clip_stack_save() and cogl_clip_stack_restore() were originally added
to allow us to save/restore the clip when switching to/from offscreen
rendering.  Now that offscreen draw buffers are defined to own their clip
state and the state will be automatically saved and restored this API is now
redundant and so deprecated.

for each interactive test. This is less than ideal, though.

Instead, the tests should build a path to the data files by using
a pre-processor define like TESTS_DATADIR; both g_build_filename() and
pre-processor string concatenation can be used to generate a valid
file name with the full path to the files.

The build system should also create wrapper scripts, just like we
do inside the conformance test suite, to be able to launch single
tests.

95d78acb4c script: Allow parsing child properties
The ClutterScript parser needs to be extended to parse child properties
and apply them after an actor has been added to a container. In order to
distinguish child properties from regular GObject properties we can use
the "child::" prefix, e.g.:

  {
    "type" : "ClutterRectangle",
    "id" : "child-01",
    "child::has-focus" : true,
    ...
  }

Parsing child properties can be deferred to the ClutterScriptable
interface, just like regular properties.

8ba13d6495 script: Clean up Color parsing rules
All the ClutterColor parsing rules should be coalesced inside
clutter_script_parse_color(): object, array and string notations
are the canonical ways of defining a ClutterColor inside a
ClutterScript definition. Having a single function in charge of
the parsing cleans up the code.

d7cfa15851 conform: Add the beginnings of a ClutterScript test suite
ClutterScript is a very complicated piece of machinery, with a
parser that has custom variations on top of the basic JSON
format; it could also be extended in the future, so if we don't
want to introduce regressions or break existing ClutterScript
definitions, we'd better have a conformance test suite.

7d891d9dd4 tests: Allow getting data files from the tests/data directory
The units under the conformance test suite should be able to use
external files. Linking the files in tests/conform like the
interactive tests do seems like a hack piled on top of a hack, so
instead we should provide a programmatic way for a conformance
test unit to get the full path of a file, regardless of where the
tests/data directory is.

We can use a define to get the full path of tests/data and then
a function using g_build_filename() to construct the path to the
file we want.

4258214e50 [test-fbo] greatly simplify the test
This test tried to do too much, and I can't remember the last time I saw this
test work.

It no longer tries to create a texture from an offscreen actor and it no
longer tries to use shaders.

It does though show that chaining of clutter_texture_new_from_actor now
works, and that animating the source actor is reflected in textures created
from it.

When run you should see three actors:
- on the left is the pristine source actor rotating around the y-axis
- in the middle is the first texture created from the source actor
- and on the right a texture created from the middle actor

Note: the somewhat strange bobbing of the middle and right textures is
actually correct given how it was decided long ago to map the transformed
(to screen space) allocation of the source actor to the texture.  When the
hand spins around the perspective projection of the top of the hand results
in the origin of the texture bobbing up to a higher stage position, but the
position of the textures is fixed.  This design also means we end up
reallocating our offscreen draw buffer every frame that the actors
transformed size changes, which isn't ideal.

ffb592de59 [tests] test-backface-culling: test culling with offscreen rendering
Since offscreen rendering is internally forced to be upside down Cogl
needs to reverse the glFrontFace winding order so as not to interfere
with the use of cogl_set_backface_culling_enabled()

This ensures we test that mechanism.

60b642f5d6 [tests] Adds test-cogl-readpixels.c for very basic cogl_read_pixels testing
Mostly this was written to verify that we don't flip the data read back from
an offscreen draw buffer.  (since all offscreen rendering is done upside
down)

2ff7f2d287 [tests] Adds test-cogl-offscreen to validate offscreen draw buffer
This adds a basic test to check that rendering a few colored rectangles
offscreen works and that the modelview gets restored when switching back to
the previous buffer.

369e68630d [tests] test-cogl-viewport tests semantics of over/under size viewports
Unlike OpenGL Cogl puts the origin of windows/viewports at the top left
instead of bottom left.  This test verifies that we correctly translate Cogl
viewports to OpenGL viewports for the awkward cases where the given viewport
has an offset and/or the viewport has a different size to the current draw
buffer.

bc24190b9a [test-texture-fbo] comment the colors defined in corner_colors
It helps to be able to quickly glance at the definition to see which
quadrant of the test actor should be which color, so when debugging a
problem and looking at the visual output you can easily verify if it's being
flipped upside down/left to right.

b41a81fb08 Add a conformance test for clutter_texture_new_from_actor
This contains four tests :-

 - A regular onscreen source with a clone next to it

 - An offscreen source with a clone. This is currently commented out
   because it no longer works.

 - An onscreen source with a rectangular clip and a clone.

 - An onscreen source with a clip from a path and a clone.

The sources are all a 2x2 grid of colors. Each clone is tested that it
either contains the color that should be at that grid position or that
the stage color is showing through if the source is clipped.
