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. https://bugzilla.gnome.org/show_bug.cgi?id=668856 Reviewed-by: Neil Roberts <neil@linux.intel.com>
