material: Split the fragment processing backends out This splits the fragment processing backends (glsl, arbfp and fixed) out from cogl-material.c into their own cogl-material-{glsl,arbfp,fixed}.c files in an effort to help and keep cogl-material.c maintainable.

Rename CoglPipelineBackend to CoglPipelineFragend The current Cogl pipeline backends are entirely concerned with the fragment processing state. We also want to eventually have separate backends to generate shaders for the vertex processing state so we need to rename the fragment backends. 'Fragend' is a somewhat weird name but we wanted to avoid ending up with illegible symbols like CoglPipelineFragmentBackendGlslPrivate.

cogl: rename CoglMaterial -> CoglPipeline This applies an API naming change that's been deliberated over for a while now which is to rename CoglMaterial to CoglPipeline. For now the new pipeline API is marked as experimental and public headers continue to talk about materials not pipelines. The CoglMaterial API is now maintained in terms of the cogl_pipeline API internally. Currently this API is targeting Cogl 2.0 so we will have time to integrate it properly with other upcoming Cogl 2.0 work. The basic reasons for the rename are: - That the term "material" implies to many people that they are constrained to fragment processing; perhaps as some kind of high-level texture abstraction. - In Clutter they get exposed by ClutterTexture actors which may be re-inforcing this misconception. - When comparing how other frameworks use the term material, a material sometimes describes a multi-pass fragment processing technique which isn't the case in Cogl. - In code, "CoglPipeline" will hopefully be a much more self documenting summary of what these objects represent; a full GPU pipeline configuration including, for example, vertex processing, fragment processing and blending. - When considering the API documentation story, at some point we need a document introducing developers to how the "GPU pipeline" works so it should become intuitive that CoglPipeline maps back to that description of the GPU pipeline. - This is consistent in terminology and concept to OpenGL 4's new pipeline object which is a container for program objects. Note: The cogl-material.[ch] files have been renamed to cogl-material-compat.[ch] because otherwise git doesn't seem to treat the change as a moving the old cogl-material.c->cogl-pipeline.c and so we loose all our git-blame history.

arbfp: Adds an ARBfp program cache This adds a cache (A GHashTable) of ARBfp programs and before ever starting to code-generate a new program we will always first try and find an existing program in the cache. This uses _cogl_pipeline_hash and _cogl_pipeline_equal to hash and compare the keys for the cache. There is a new COGL_DEBUG=disable-program-caches option that can disable the cache for debugging purposes.
