    Move GLES2 prototypes to their header
    
    Some GLSL-related function prototypes are GLES2-only: GL implementations
    are not required to provide them.
    
    While Mesa is perfectly happy to return a dummy function pointer for
    functions it doesn't support, other platforms are more picky, and will
    return NULL.
    
    In this particular case, this commit fixes GLSL support on OSX.
