eff82a546d [gles/cogl-shader] Add a missing semicolon
cogl_shader_get_info_log was missing a semicolon which broke the build
on GLES 2.

c20886c5e3 [gles/cogl-shader] Fix parameter spec for cogl_shader_get_info_log
The stub version of cogl_shader_get_info_log needed to be updated to
match the changes to the function signature in 61deeafa.

61deeafa71 [cogl-shader] Make get_info_log() slightly nicer
The cogl_shader_get_info_log() function is very inconvenient for
language bindings and for regular use, as it requires a static
buffer to be filled -- basically just providing a wrapper around
glGetInfoLogARB().

Since COGL aims to be a more convenient API than raw GL we should
just make cogl_shader_get_info_log() return an allocated string
with the GLSL compiler log.

36cfb60307 [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cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and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.

f85377372c [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

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.

Bug 1219 - Clean up cogl.h

	* clutter/cogl/cogl.h.in:
	* clutter/cogl/cogl-offscreen.h:

	* clutter/cogl/cogl-shader.h:
	* clutter/cogl/cogl-texture.h:
	* clutter/cogl/cogl-types.h: Split up the massive cogl.h file
	into sub-header for each section of the API.

	* clutter/cogl/gl/*:
	* clutter/cogl/gles/*: Update the GL and GLES implementations
	of COGL to cope with the new header structure.

	* doc/reference/cogl/Makefile.am: Fix symbol retrieval.

42ed195f01 * clutter/cogl/gles/cogl-gles2-wrapper.h: The uniform numbers are
now stored in a separate struct so they can be stored for
	application program objects as well.

	* clutter/cogl/gles/cogl.c: Moved stub shader functions into
	separate files.
	(_cogl_features_init): Report support for the shaders feature on
	GLES 2

	* clutter/cogl/gles/cogl-shader.h:
	* clutter/cogl/gles/cogl-shader.c:
	* clutter/cogl/gles/cogl-program.h:
	* clutter/cogl/gles/cogl-program.c: Separate files to handle
	shaders on programs on GLES. If version 1.1 is being used then the
	stub functions which all fail are still used.

	* clutter/cogl/gles/cogl-gles2-wrapper.c
	(cogl_gles2_wrapper_init, cogl_gles2_wrapper_bind_attributes),
	(cogl_gles2_wrapper_get_uniforms): Move the uniforms and attribute
	bindings into a separate function so they can be used to bind on
	application shaders as well.
	(cogl_gles2_wrapper_update_matrix): Now takes a parameter and is
	no longer static so that it can be used to update all of the
	matrices when a new shader is bound.

	* clutter/cogl/gles/cogl-defines.h.in: Use GL_COMPILE_STATUS for
	CGL_OBJECT_COMPILE_STATUS if the latter isn't available (for
	example on GLES 2).

	* clutter/cogl/gles/cogl-context.h (CoglContext): Added handle
	arrays for programs and shaders.

	* clutter/cogl/gles/cogl-context.c (cogl_create_context)
	(cogl_destroy_context): Initialize and destroy program and shader
	handle array.

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