ec02a8808e deform-effect: Use the FBO target size
The ClutterDeformEffect sub-classes are effectively deforming the
texture target of an FBO, not the actor itself. Thus, we need to
use the FBO's size, and not the actor's allocated size, given that
the actor might be transformed prior to applying an effect.

20f19fe06c offscreen-effect: Add private API for getting the target size
Since the FBO target might have a different size than the mere paint box
of the actor, we need API to get it out of the ClutterOffscreenEffect
private data structure and on to sub-classes.

Since we cannot add new API in a stable cycle, we need a private
function; we'll leave it there even when opening 1.7, since it's useful
for internal purposes.

bc548dc862 Store the motion event deliver flag in ClutterStage
Once upon a time, the land of Clutter had a stage singleton. It was
created automatically at initialization time and stayed around even
after the main loop was terminated. The singleton was content in
being all there was. There also was a global API to handle the
configuration of the stage singleton that would affect the behaviour
on other classes, signals and properties.

Then, an evil wizard came along and locked the stage singleton in his
black tower, and twisted it until it was possible to create new stages.
These new stages were pesky, and didn't have the same semantics of the
singleton: they didn't stay around when closed, or terminate the main
loop on delete events.

The evil wizard also started moving all the stage-related API from the
global context into class-specific methods.

Finally, the evil wizard cast a spell, and the stage singleton was
demoted to creation on demand - and until somebody called the
clutter_stage_get_default() function, the singleton remained in a limbo
of NULL pointers and undefined memory areas.

There was a last bit - literally - of information still held by the
global API; a tiny, little flag that disabled per-actor motion events.
The evil wizard added private accessors for it, and stored it inside the
stage private structure, in preparation for a deprecation that would
come in a future development cycle.

The evil wizard looked down upon the land of Clutter from the height of
his black tower; the lay of the land had been reshaped into a crucible
of potential, and the last dregs of the original force of creation were
either molted into new, useful shapes, or blasted away by the sheer fury
of his will.

All was good.

fc89513295 actor: Move the ShaderData out of the private data
Let's try and start reducing the size of ClutterActorPrivate by moving
some optional, out-of-band data from it to GObject data.

The ShaderData structure is a prime candidate for this migration: it
does not need to be inspected by the actor, and its relationship with an
actor is transient and optional.

By attaching it to the actor's instance through g_object_set_data() we
neatly tie its lifetime to the instance, and we don't have to care
cleaning it up in the finalize()/dispose() implementation of
ClutterActor itself.

9ea2567a2f cogl-atlas-texture: Don't let textures be destroyed during migration
If an atlas texture's last reference is held by the journal or by the
last flushed pipeline then if an atlas migration is started it can
cause a crash. This is because the atlas migration will cause a
journal flush and can sometimes change the current pipeline which
means that the texture would be destroyed during migration.

This patch adds an extra 'post_reorganize' callback to the existing
'reorganize' callback (which is now renamed to 'pre_reorganize'). The
pre_reorganize callback is now called before the atlas grabs a list of
the current textures instead of after so that it doesn't matter if the
journal flush destroys some of those textures. The pre_reorganize
callback for CoglAtlasTexture grabs a reference to all of the textures
so that they can not be destroyed when the migration changes the
pipeline. In the post_reorganize callback the reference is removed
again.

e90ded6c23 cogl-atlas: Try 4 different approaches for migrating textures
Instead of directly banging GL to migrate textures the atlas now uses
the CoglFramebuffer API. It will use one of four approaches; it can
set up two FBOs and use _cogl_blit_framebuffer to copy between them;
it can use a single target fbo and then render the source texture to
the FBO using a Cogl draw call; it can use a single FBO and call
glCopyTexSubImage2D; or it can fallback to reading all of the texture
data back to system memory and uploading it again with a sub texture
update.

Previously GL calls were used directly because Cogl wasn't able to
create a framebuffer without a stencil and depth buffer. However there
is now an internal version of cogl_offscreen_new_to_texture which
takes a set of flags to disable the two buffers.

The code for blitting has now been moved into a separate file called
cogl-blit.c because it has become quite long and it may be useful
outside of the atlas at some point.

The 4 different methods have a fixed order of preference which is:

* Texture render between two FBOs
* glBlitFramebuffer
* glCopyTexSubImage2D
* glGetTexImage + glTexSubImage2D

Once a method is succesfully used it is tried first for all subsequent
blits. The default default can be overridden by setting the
environment variable COGL_ATLAS_DEFAULT_BLIT_MODE to one of the
following values:

* texture-render
* framebuffer
* copy-tex-sub-image
* get-tex-data

code. Even with the restrictions, the extension provides enough

80bae51c01 cogl-atlas-texture: Make copying a texture out more robust
Previously when _cogl_atlas_texture_migrate_out_of_atlas is called it
would unreference the atlas texture's sub-texture before calling
_cogl_atlas_copy_rectangle. This would leave the atlas texture in an
inconsistent state during the copy. This doesn't normally matter but
if the copy ends up doing a render then the atlas texture may end up
being referenced. In particular it would cause problems if the texture
is left in a texture unit because then Cogl may try to call
get_gl_texture even though the texture isn't actually being used for
rendering. To fix this the sub texture is now unrefed after the copy
call instead.

e57aa3ca3e cogl-framebuffer: Separate the draw and read buffer
The current framebuffer is now internally separated so that there can
be a different draw and read buffer. This is required to use the
GL_EXT_framebuffer_blit extension. The current draw and read buffers
are stored as a pair in a single stack so that pushing the draw and
read buffer is done simultaneously with the new
_cogl_push_framebuffers internal function. Calling
cogl_pop_framebuffer will restore both the draw and read buffer to the
previous state. The public cogl_push_framebuffer function is layered
on top of the new function so that it just pushes the same buffer for
both drawing and reading.

When flushing the framebuffer state, the cogl_framebuffer_flush_state
function now tackes a pointer to both the draw and the read
buffer. Anywhere that was just flushing the state for the current
framebuffer with _cogl_get_framebuffer now needs to call both
_cogl_get_draw_buffer and _cogl_get_read_buffer.

2ee7052d89 cogl-framebuffer: Fix flushing the framebuffer on push
When pushing a framebuffer it would previously push
COGL_INVALID_HANDLE to the top of the framebuffer stack so that when
it later calls cogl_set_framebuffer it will recognise that the
framebuffer is different and replace the top with the new
pointer. This isn't ideal because it breaks the code to flush the
journal because _cogl_framebuffer_flush_journal is called with the
value of the old pointer which is NULL. That function was checking for
a NULL pointer so it wouldn't actually flush. It also would mean that
if you pushed the same framebuffer twice we would end up dirtying
state unnecessarily. To fix this cogl_push_framebuffer now pushes a
reference to the current framebuffer instead.

ef4688fd0e Avoid direct access to the main context events queue

  • ClutterStage::dispose cleans up the events associated with

  • the queue is destroyed in ClutterBackend::dispose.

inside ClutterBackendPrivate, hence it should stay in ClutterMainContext;

734a236a97 wayland: fix shm buffers
We need to *write* to the shared memory, not read from it.
cogl_texture_from_data() is read-only, it doesn't keep
the data in sync with the texture.

Instead, we have to call cogl_texture_get_data() ourselves
to sync manually.

20b1350614 wayland: check for egl extensions explicitly
eglGetProcAddress() returns non-null function pointers
whether or not they're actually supported by the driver,
since it can be used before any driver gets loaded. So
we have to check if the extensions are advertised first,
which requires having an initialized display, so we split
the display creation code into its own function.

The exception to extension-checking is EGL_MESA_drm_display,
since by definition it's needed before any display is even
created.

9090070a98 x11: Refresh key mapping when notified by X11
Use both the MappingNotify event and the XKB XkbMapNotify event, if
we're compiled with XKB support.

This change is also useful for making ClutterKeymapX11 an event
translator and let it deal with XKB events internally like we do for
stage and input events.

55e26e23df cogl-vertex-buffer: Use a ref count on the pipeline private data
The pipeline private data is accessed both from the private data set
on a CoglPipeline and the destroy notify function of a weak material
that the vertex buffer creates when it needs to override the wrap
mode. However when a CoglPipeline is destroyed, the CoglObject code
first removes all of the private data set on the object and then the
CoglPipeline code gets invoked to destroy all of the weak children. At
this point the vertex buffer's weak override destroy notify function
will get invoked and try to use the private data which has already
been freed causing a crash.

This patch instead adds a reference count to the pipeline private data
stuct so that we can avoid freeing it until both the private data on
the pipeline has been destroyed and all of the weak materials are
destroyed.

5740a5a38a cogl-pipeline: Fix comparing the color in set_layer_combine_constant
In cogl_pipeline_set_layer_combine_constant it was comparing whether
the new color is the same as the old color using a memcmp on the
constant_color parameter. However the combine constant is stored in
the layer data as an array of four floats but the passed in color is a
CoglColor (which is currently an array of four guint8s). This was
causing valgrind errors and presumably also the check for setting the
same color twice would always fail.

This patch makes it do the conversion to a float array upfront before
the comparison.

2ded18933e cogl-matrix: Get rid of the *_packed variants
cogl_matrix_project_points and cogl_matrix_transform_points had an
optimization for the common case where the stride parameters exactly
match the size of the corresponding structures. The code for both when
generated by gcc with -O2 on x86-64 use two registers to hold the
addresses of the input and output arrays. In the strided version these
pointers are incremented by adding the value of a register and in the
packed version they are incremented by adding an immediate value. I
think the difference in cost here would be negligible and it may even
be faster to add a register.

Also GCC appears to retain the loop counter in a register for the
strided version but in the packed version it can optimize it out and
directly use the input pointer as the counter. I think it would be
possible to reorder the code a bit to explicitly use the input pointer
as the counter if this were a problem.

Getting rid of the packed versions tidies up the code a bit and it
could potentially be faster if the code differences are small and we
get to avoid an extra conditional in cogl_matrix_transform_points.

634e4ffd1a osx: Improve the event loop
Implementation of event loop which works with GLib events, native OS X
events and Clutter events.

The event loop source code comes from the equivalent code in the Quartz
GDK backend from GTK+ 2.22.1, which is LGPL v2.1+ and thus compatible
with Clutter's licensing terms.

The code has been tested with libsoup, which did not work before together
with Clutter.

Wayland visuals refer to a pixel's bytes in order from
