GtkGLArea doesn't provide the RGB colormap sharing support.

I've started the new OpenGL support library, GtkGLExt
(http://gtkglext.sourceforge.net/), because GtkGLArea have no real
maintainer and it is buggy.

Anyway, to implement the RGB colormap sharing feature using the ICCCM
conventions, fixed gdkx_colormap_get() or something is needed.
