It was at first thought that the a copy of the GL frame buffer would
have to be passed, then disable the direct rendering context and grab
the X root then bltt.  But read below...

It turns out it is a bug in X and I'm working on a solution at the real
problem.  It's a return ( or was it never fixed? ) of the X_QueryColors
bug, that just happened to affect xwd and other apps used by said teams
independently.  I've got a hack solution for xwd right now, and I'm
getting the source to patch it this week.  By the way I found this out
via IRIX documentation and some traces, if anyone else has this problem
with overlays/OpenGL/etc in the future.  =)

Sorry about that guys, everyone jumped at once when several projects had
the same issue...  wolf indeed  ;)

cheers,
Terry
