c3d9f0bed4 [cogl-handle] Optimize how we define cogl handles
The cogl_is_* functions were showing up quite high on profiles due to
iterating through arrays of cogl handles.

This does away with all the handle arrays and implements a simple struct
inheritance scheme. All cogl objects now add a CoglHandleObject _parent;
member to their main structures. The base object includes 2 members a.t.m; a
ref_count, and a klass pointer. The klass in turn gives you a type and
virtual function for freeing objects of that type.

Each handle type has a _cogl_##handle_type##_get_type () function
automatically defined which returns a GQuark of the handle type, so now
implementing the cogl_is_* funcs is just a case of comparing with
obj->klass->type.

Another outcome of the re-work is that cogl_handle_{ref,unref} are also much
more efficient, and no longer need extending for each handle type added to
cogl. The cogl_##handle_type##_{ref,unref} functions are now deprecated and
are no longer used internally to Clutter or Cogl. Potentially we can remove
them completely before 1.0.

08932584b5 Virtualize GL matrix operations and use a client-side matrix when GL is indirect
This is useful because sometimes we need to get the current matrix, which
is too expensive when indirect rendering.

In addition, this virtualization makes it easier to clean up the API in
the future.

* clutter/cogl/gl/cogl.c: 
	* clutter/cogl/gles/cogl.c: 
	* clutter/cogl/cogl.h.in: Add cogl_clip_stack_save,
	cogl_clip_stack_restore, cogl_viewport and cogl_frustum.

3d034ff6aa cogl: define GL_READ/DRAW_FRAMEBUFFER_EXT if not available
Bug 913 - cogl fails to build on OSX

	* clutter/cogl/gl/cogl-fbo.c: define GL_READ_FRAMEBUFFER_EXT and
	GL_DRAW_FRAMEBUFFER_EXT if not defined in the build system. The
	#ifdef can fail if they're not #defines but variables or enums.
	As the values are supposed to be industry standard even then
	it shouldn't have ill effects.

19058afe82 Removed COGLhandle and changed shader and program functions to be
wrapped in reference-counted CoglHandles instead.

	* clutter/cogl/gl/cogl-shader.c: 
	* clutter/cogl/gl/cogl-shader.h: 
	* clutter/cogl/gl/cogl-program.c: 
	* clutter/cogl/gl/cogl-program.h: 
	New files to hold the shader and program functions.

	* clutter/cogl/gl/cogl.c: Removed shader and program functions.

	* clutter/cogl/common/cogl-handle.h: New header to define
	COGL_HANDLE_DEFINE which helps build functions to create
	reference-counted handles. This reduces the amount of duplicated
	code.

	* clutter/cogl/gl/cogl-texture.c: 
	* clutter/cogl/gles/cogl-texture.c: 
	* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE
	from cogl-handle.h to avoid duplicating some of the common code.

	* clutter/cogl/gles/cogl-defines.h.in: 
	* clutter/cogl/gl/cogl-defines.h.in: Removed COGLhandle

	* clutter/cogl/gl/cogl-context.h: Added handle arrays for programs
	and shaders.

	* clutter/cogl/gl/cogl-context.c (cogl_create_context): Added
	initialisers for shader_handles and program_handles.
	(cogl_destroy_context): Added calls to g_array_free for all handle
	arrays.

	* clutter/cogl/gl/Makefile.am (libclutter_cogl_la_SOURCES): Added
	cogl-{program,shader}.{c,h}

	* clutter/cogl/common/Makefile.am
	(libclutter_cogl_common_la_SOURCES): Added cogl-handle.h

	* clutter/cogl/gles/cogl.c:
	* clutter/cogl/cogl.h.in: Programs and shaders are now wrapped in
	CoglHandles instead of COGLhandles. cogl_program_destroy and
	cogl_shader_destroy is now replaced with cogl_program_unref and
	cogl_shader_unref. cogl_program_ref and cogl_shader_ref are also
	added.

	* clutter/clutter-shader.c: Converted to use CoglHandles for the
	programs and shaders instead of COGLhandles.

	* cogl/cogl-sections.txt: Added cogl_shader_ref,
	cogl_shader_unref, cogl_is_shader, cogl_program_ref,
	cogl_program_unref, cogl_is_program and cogl_is_offscreen.
