885942aec0 cogl-pipeline-fragend-arbfp: Generate ARBfp if user vertex shader
The ARBfp fragend was bypassing generating a shader if the pipeline
contains a user program. However it shouldn't do this if the pipeline
only contains a vertex shader. This was breaking
test-cogl-just-vertex-shader.

dc1f1949d0 Remove the GLES2 wrapper
The GLES2 wrapper is no longer needed because the shader generation is
done within the GLSL fragend and vertend and any functions that are
different for GLES2 are now guarded by #ifdefs.

2b32a9eb2a cogl-pipeline: Use enums for the layer combine values
Once the GLES2 wrapper is removed then we won't have the GLenums
needed for setting up the layer combine state. This adds Cogl enums
instead which have the same values as the corresponding GLenums. The
enums are:

CoglPipelineCombineFunc
CoglPipelineCombineSource
 and
CoglPipelineCombineOp

fa13f6c107 cogl: Add a vertend to generate GLSL
The GLSL vertend is mostly only useful for GLES2. The fixed function
vertend is kept at higher priority than the GLSL vertend so it is
unlikely to be used in any other circumstances.

0c732c27ae cogl-pipeline: Rename the fragment_{source,header}_buffer to codegen
We want to reuse the same buffers for vertends so calling them
fragment_* doesn't make sense.

7562a17685 cogl-pipeline: Make find codegen authority more general
The pipeline function _cogl_pipeline_find_codegen_authority has been
renamed to _cogl_pipeline_find_equivalent_parent and it now takes a
set of flags for the pipeline and layer state that affects the
authority. This is needed so that we can reuse the same code in the
vertend and progends.

6b7139b008 cogl-pipeline: Move texture enabling/disabling to fixed fragend
Previously enabling and disabling textures was done whatever the
backend in cogl-pipeline-opengl. However enabling and disabling
texture targets only has any meaning if no fragment shaders are being
used so this patch moves the code to cogl-pipeline-fragend-fixed.

The GLES2 wrapper has also been changed to ignore enabledness when
deciding whether to update texture coordinate attribute pointers.

0098dc7acc 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.
