* cogl_get_*_matrix were changed to use the CoglMatrix type instead of
GLfloat m[16] arrays.
* cogl_offscreen_blit_region, cogl_offscreen_blit were removed since they were
only implemnted for GL, not GLES, and it was assumed no one was using them.
* cogl_offscreen_new_multisample was removed since it only ever returned
COGL_INVALID_HANDLE so it wasn't usefull.
* The COGL_MASK_BUFFER type was removed, since there should be nicer ways of
exposing color mask if anyone wants it later. It was assumed that no one was
using this currently.
* 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* cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and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.
