Neil Roberts cb7a99ac69 cogl-gles2-wrapper: Add support for the layer combine operations
The texture layer combine functions are now hard coded to GL_COMBINE
instead of GL_MODULATE. The combine function can be customized with
all the parameters of GL_COMBINE. A shader is generated to implement
the given parameters.

Currently it will try to generate code for the constant color but it
will use a uniform which does not exist.
