b61c2b510b build: Tweak internal defines for building Clutter
When building Clutter we should:

  • disable Cogl deprecated API;
  • enable experimental API.

4a9f08639f debug: Adds CLUTTER_DEBUG=disable-swap-events option
This allows us to forcibly disable the use of the GLX_INTEL_swap_events
extension for testing or debugging purposes.

5d702853b8 glx backend: Adds support for GLX_INTEL_swap_event
If your OpenGL driver supports GLX_INTEL_swap_event that means when
glXSwapBuffers is called it returns immediatly and an XEvent is sent when
the actual swap has finished.

Clutter can use the events that notify swap completion as a means to
throttle rendering in the master clock without blocking the CPU and so it
should help improve the performance of CPU bound applications.

848db1ee4c glx backend: when running with GLX 1.3 then create GLXWindows for stages
Some extensions only support GLX versions > 1.3 and may not support
old style X Windows as GLXDrawables, so we now create GLXWindows for
stages when possible.

ca3ab41a1b clutter-backend: Fix the error check in _clutter_backend_create_stage
Commit d2bdd3cb62 fixed some compiler warnings but also broke the
ability to create a stage. Although not having warnings from the
compiler is nice, it is also nice to be able to create a stage so lets
not invert the meaning of the error check.

a02253f19a cogl-texture-2d: Use _cogl_texture_driver_gen to generate the GL tex
_cogl_texture_driver_gen is needed to set the texture minification
mode to Cogl's default of GL_LINEAR. There was also a line to set this
in _cogl_texture_2d_new_with_size but it wasn't working because it was
called *before* the texture was bound. If the texture was later
rendered with the default material it then it would end up with GL's
default mipmap filtering mode but without mipmaps so it would render
white squares instead.

1b2ff7eff7 cogl: Use SSE2 when possible for premultiplying
This adds a fast path for premultiplying an RGBA image using SSE2
instructions. SSE registers are 128-bit and we need at least 16-bits
per component for the intermediate result of the multiplication so we
can do two pixels in parallel with one register. The function
interleaves 2 SSE registers to multiply 4 pixels in one function call
with the hope that this will pipeline better.

d0fe479536 cogl-pixel-buffer: Add a fallback path
First, let's add a new public feature called, surprisingly,
COGL_FEATURE_PBOS to check the availability of PBOs and provide a
fallback path when running on older GL implementations or on OpenGL ES

In case the underlying OpenGL implementation does not provide PBOs, we
need a fallback path (a malloc'ed buffer). The CoglPixelBufer
constructors will instanciate a subclass of CoglBuffer that handles
map/unmap and set_data() with a malloc'ed buffer.

The public feature is useful to check before using set_data() on a
buffer as it will mean doing a memcpy() when not supporting PBOs (in
that case, it's better to create the texture directly instead of using a
CoglBuffer).

abbb668163 cogl-pixel-buffer: add a pixel buffer object class
This subclass of CoglBuffer aims at wrapping PBOs or other system
surfaces like DRM buffer objects. Two constructors are available:

cogl_pixel_buffer_new() with a size when you only care about the size of
the buffer (such a buffer can be used to store several texture data such
as the three planes of a I420 frame).

cogl_pixel_buffer_new_full() is more a 1:1 mapping between the data and
an underlying surface, with the possibility of having access to a low
level memory buffer that may have a stride.

b5e9710cdf cogl-buffer: add an abstract class around openGL's buffer objects
Buffer objects are cool! This abstracts the buffer API first introduced
by GL_ARB_vertex_buffer_object and then extended to other objects.

The coglBuffer abstract class is intended to be the base class of all
the buffer objects, letting the user map() buffers. If the underlying
implementation does not support buffer objects (or only support VBO but
not FBO for instance), fallback paths should be provided.

de8a6314f1 cogl: new textures sould have GL_TEXTURE_MIN_FILTER set to GL_LINEAR
The only way the user has to set the mipmap filters is through the
material/layer API. This API defaults to GL_LINEAR/GL_LINEAR for the max
and min filters. With the main use case of cogl being 2D interfaces, it
makes sense do default to GL_LINEAR for the min filter.

When creating new textures, we did not set any filter on them, using
OpenGL defaults': GL_NEAREST_MIPMAP_LINEAR for the min filter and
GL_LINEAR for the max filter. This will make the driver allocate memory
for the mipmap tree, memory that will not be used in the nominal case
(as the material API defaults to GL_LINEAR).

This patch tries to ensure that the min filter is set to GL_LINEAR
before any glTexImage*() call is done on the texture by setting the
filter when generating new OpenGL handles.

790a13c0d9 animator: Allow retrieving type property type from a key
When asking a key for its target value we also ask the developer to pass
in an initialized GValue - but we don't make it easy to know the type of
the GValue. A developer has to ask the GObject class for the GParamSpec
and then initialize the GValue, instead.

Since we know the type of the GValue we should provide a getter for it.

We should also allow developers to throw at us GValue with compatible and
transformable types.

Finally, all the accessors should be constified.

09f91ff6ea script: Use a node when resolving an animation mode
Instead of taking a string and duplicating the "is it a string or an

JsonNode and do all the checks it needs.

cc6aefad34 cogl path: make sure marking the clip state dirty takes affect
When we trashed the contents of the stencil buffer during
_cogl_path_fill_nodes we marked the clip stack state as dirty and expected
the clip stack code would clean up our glStencilFunc state.

The problem is that we only try and update the clip state during
_cogl_journal_init (when we flush the framebuffer state) which is only
called when the journal first gets something logged in it.

To make sure the stencil state is cleaned up we now also flush the journal
so _cogl_journal_init will be called for the next logged rectangle.

24338a7511 clutter-master-clock: Don't wait for a frame if time goes backwards
If we aren't syncing to vblank or if the last dispatch didn't cause a
redraw then the master clock will try to wait at least a small amount
of time before dispatching again. However if time goes backwards then
it would not do a dispatch until time catches up again. To fix this it
know just runs a dispatch immediately if time goes backwards.

This is related to Moblin bug #3839. There was a similar fix for this
in 9dc012c07, however that only fixed the case where timelines
wouldn't update. If there are no animations running then the master
clock won't even try updating timelines until time catches up.

4cc269a468 Add ClutterAnimator
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.

b968defae9 [stage] Set default size correctly
Due to the way the new sizing works, clutter stage must set its size in
init (to maintain old behaviour) and the properties on the X11 stage
must be initialised to 1x1 so that it actually goes ahead with the
resize.

Fixes stages that aren't user resizable and have no size set from
appearing at 1x1.

29cc027f06 [x11] Don't set actor size on ConfigureNotify
Calling clutter_actor_set_size in response to ConfigureNotify makes
setting the size of the stage racy - the most common result of which
seems to be that you can't set the stage dimensions to anything less
than 640x480.

Instead, add a first_allocation bit to the private structure of the X11
stage and force the first resize (necessary or the default stage will be
a 1x1 window).

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.
