dnl GL inclusion and link. We depend on GL for the single glGetIntegerv()

dnl call. The end goal is to get rid of it, but we can't just yet.

dnl For now, we assume Clutter/Cogl includes the GL headers (whatever they

dnl are). By the time they don't do that, we'll hopefully won't have any

dnl direct GL dependency.

dnl As for linking against -lGL, I believe Clutter always end up puttin libGL

dnl in its exported CFLAGS, except when compiling against the NVidia library

dnl (which does not have the 'gl' .pc file. For now, let's just add -lGL when

dnl we are using the glx flavour, That should fix the vast majority of the

dnl issues

dnl Why don't we "just" link against GL? check the cogl/clutter configure.ac :)

dnl Hopefully this will be enough for the time being.

dnl With Cogl 1.8.0 all of the above is moot because we can use

dnl cogl_renderer_get_n_fragment_texture_units() and never depend on GL/GLES

dnl directly. However let's not hard depend on cogl 1.8.0 just yet.

dnl Well, obviously just a little detail remaining, it's not possible to grab

dnl the CoglContext on OS X yet.
