Ah, yes: the configure script stops if it can't find GTK+. Indeed
that's undesirable. I'll fix that.

Well, problem is I don't known what functions to interface. As I
understand things, most functions in glitz.h provide a similar API to
cairo's and are here to be called by the glitz backend in cairo. So I
guess that if I wrap the couple of functions in glitz-glx.h and
glitz-agl.h that return a glitz_surface_t, that would make the glitz
cairo backend usable from caml. Is that correct ?
