I'm not familiar with ARGB visuals at all, so the question is, how do
they fit in with GLX?  If it is just a new visual attribute that can be
requested just like "alpha", "stencil", "double-buffer", etc. then it
can be added to the GdkGLConfigMode enumeration.  Is ARGB distinct from
RGBA (there's an unused option for RGBA already)?
