Bug 1219 - Clean up cogl.h * clutter/cogl/cogl.h.in: * clutter/cogl/cogl-offscreen.h: * clutter/cogl/cogl-path.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.
