671ead6681 Rename cogl_framebuffer_swap_* apis to cogl_onscreen_swap_*
Recently the cogl_framebuffer_swap_* apis were moved into the
cogl_onscreen_* namespace since only CoglOnscreen framebuffers can be
double buffered. This renames all uses of the cogl_framebuffer_swap_*
apis in Clutter.

fbf94310fc Pass a CoglContext when calling cogl_pipeline_new
The experimental cogl_pipeline_new() api was recently changed so it
explicitly takes a CoglContext. This updates all calls to
cogl_pipeline_new() in clutter accordingly.

9c038ebefb stage-window: Add :backend and :wrapper properties
All StageWindow implementation already have back pointers, but we need a
unified API to actually set them from the generic code path; we can use
properties on the StageWindow interface — though this requires fixing
all backends at the same time, to avoid GObject complaining.

5c9cafb411 cogl/backend: Remove the ClutterBackendCogl class
All the functionality that ClutterBackendCogl provided has been moved
into ClutterBackend itself, so there is no need to have this class
around in the source.

Cogl-based backends can derive directly from ClutterBackend.

a09bbffd92 Implement multi-backend support
The Clutter backend split is opaque enough that should allow us to just
build all possible backends inside the same shared object, and select
the wanted backend at initialization time.

This requires some work in the build system, as well as the
initialization code, to remove duplicate functions that might cause
conflicts at build and link time. We also need to defer all the checks
of the internal state of the platform-specific API to run-time type
checks.

9c102b7c51 Rework the interaction between the Cogl and GDK / X11 backends.
Previously, the Cogl backend was at times a subclass of the X11
backend, and at times a standalone one. Now it is the other way
round, with GDK and X11 backends providing the concrete classes,
layered on top of the generic Cogl backend. A new EglNative backend
was introduced for direct to framebuffer rendering. This greatly
simplifies the API design (at the expense of some casts needed)
and reduces the amount of #ifdefs, without duplicating code.

610a9c17ba Add a new GDK backend
This commit introduces a new flavour for Clutter, that uses GDK
for handling all window system specific interactions (except for
creating the cogl context, as cogl does not know about GDK), including
in particular events. This is not compatible with the X11 (glx)
flavour, and this is reflected by the different soname (libclutter-gdk-1.0.so),
as all X11 specific functions and classes are not available. If you
wish to be compatible, you should check for CLUTTER_WINDOWING_X11.
Other than that, this backend should be on feature parity with X11,
including XInput 2, XSettings and EMWH (with much, much less code)

6e28121ff3 cogl: include <cogl/cogl-xlib.h> for xlib specific symbols
Since Xlib.h is such a terrible citizen when it comes to symbol
namespacing it's not desirable to include Xlib.h if it is not absolutely
required. Cogl now has a standalone cogl-xlib.h that should be included
whenever any xlib specific symbols are required.

This patch updates clutter to include <cogl/cogl-xlib.h> wherever
clutter needs to use xlib specific cogl apis.

The g_atexit() function has been deprecated in GLib as it is a fairly

We could probably use a GCC destructor if we didn't care about

d2763fd8a4 stage-cogl: pass top-left relative swap_region coords
All 2D coordinate spaces in Cogl have their origin at the top-left so we
shouldn't be flipping the coordinates we pass to
cogl_framebuffer_swap_region to be relative to the bottom of the
framebuffer.

This bumps the Cogl version requirement to 1.7.5 since we've had to fix
a bug in the semantics of cogl_framebuffer_swap_region.

672bc337ba build: don't explicitly include and egl or gl headers
This avoids explicitly including gl or egl headers in
clutter-egl-headers.h. We were getting build failures when building
clutter against a libcogl that has runtime support for GL and GLES
because cogl-defines.h was including gl.h and then clutter-egl-headers.h
was later including GLES2/gl.h with typedef conflicts. Clutter relies on
Cogl to abstract GL and GLES and the winsys APIs like EGL and GLX so
Clutter should just rely on cogl.h to include the appropriate egl.h in
clutter-egl-headers.h.

a72237b876 clutter-stage: Add clutter_stage_get_redraw_clip_bounds
This adds a public function to get the bounds of the current clipped
redraw on a stage. This should only be called while the stage is being
painted. The function diverts to a virtual function on the
ClutterStageWindow implementation. If the function isn't implemented
or it returns FALSE then the entire stage is reported. The clip bounds
are in integer pixel coordinates in the stage's coordinate space.

the EGL backend) used g_warning to report the feature as unsupported and
that was causing conformance test failures.

2d8083bab8 unify egl and glx backends as "cogl" backend
Since GLX and EGL are abstracted by Cogl the two backends are both
implementing everything using the Cogl API and they are almost
identical.

This updates the egl backend to support everything that the glx backend
supports. Now that EGL and GLX are abstracted by Cogl, the plan is that
we will squash the clutter-egl/glx backends into one. Since the EGL
backend in clutter can conditionally not depend on X11 we will use the
EGL backend as the starting point of our common backend.

77cd2ca08e cogl_pipeline_equal: Handle COGL_WRAP_MODE_AUTOMATIC better
When comparing the wrap modes of two pipeline layers it now considers
COGL_WRAP_MODE_AUTOMATIC to be equivalent to CLAMP_TO_EDGE. By the
time the pipeline is in the journal, the upper primitive code is
expected to have overridden this wrap mode with something else if it
wants any other behaviour. This is important for getting text to batch
together with textures because the text explicitly sets the wrap mode
to CLAMP_TO_EDGE on its pipeline.

41e464fc9e cogl-pango: Don't set the special combine function for atlased textures
The material cache will now only set the special combine mode if the
texture only has an alpha component. The atlased textures will have
all four components so it will leave the combine functions at the
default. This increases the chances of batching between glyphs and
images.

When using the global atlas, the glyph from cairo is now rendered into
an ARGB surface rather than an alpha-only surface.

9083fc8e1f cogl-pango: Use a seperate cache of pipelines
Instead of creating just two materials (one for texturing and one for
solid primitives) the pango renderer now maintains a cache of
pipelines. The display list can request a pipeline for a texture from
the cache. The same pipeline cache is used by all display lists so
that the pipelines can be shared. This avoids changing the texture on
the material during a paint run.

22ce8a7111 cogl-pango-glyph-cache: Don't put zero-sized glyphs in the cache
It now avoids trying to reserve space for zero-sized glyphs. That
happens for example when the layout contains a space. This was causing
the regular glyph cache to be used because the global atlas does not
support zero-sized images. That would then break up the
batching. Instead it now still reserves an entry in the cache but
leaves the texture as COGL_INVALID_HANDLE.
