6db0d42193 [cogl] Remove the COGL{enum,int,uint} typedefs
COGLenum, COGLint and COGLuint which were simply typedefs for GL{enum,int,uint}
have been removed from the API and replaced with specialised enum typedefs, int
and unsigned int. These were causing problems for generating bindings and also
considered poor style.

The cogl texture filter defines CGL_NEAREST and CGL_LINEAR etc are now replaced
by a namespaced typedef 'CoglTextureFilter' so they should be replaced with
COGL_TEXTURE_FILTER_NEAREST and COGL_TEXTURE_FILTER_LINEAR etc.

The shader type defines CGL_VERTEX_SHADER and CGL_FRAGMENT_SHADER are handled by
a CoglShaderType typedef and should be replaced with COGL_SHADER_TYPE_VERTEX and
COGL_SHADER_TYPE_FRAGMENT.

cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and
cogl_shader_is_compiled. More getters can be added later if desired.

7e9685294e [cogl] Updates all file headers and removes lots of trailing white space
Adds missing notices, and ensures all the notices are consistent. The Cogl
blurb also now reads:

 * Cogl
 *
 * An object oriented GL/GLES Abstraction/Utility Layer

ed272213f0 [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.

0e0890a2e9 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}

	(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.
