commit def67a39fe9ca2c270af9a1a17e377a65829bb2f
Author: Robert Bragg <robert linux intel com>
Date: Sun Jan 1 21:45:07 2012 +0000
gl-prototypes: split up cogl-ext-functions.h
This splits up cogl-ext-functions.h in to sets of prototypes that
can be included separately so that we can include just core
gles1 or gles2 functions without any extensions.
Since eglGetProcAddress can not be used to query core client APIs
and some implementations (notably on Android) can return a garbage
pointer instead of NULL this will allow us to explicitly check
when to use eglGetProcAddress and when to use dlsym().
