I fear this is a FAQ, but is it possible to get double and single buffering
using the technology of GlxDraw widget. I understand how one has two windows
for overlay planes and normal planes, using GLXwinset to go between them,
but is it possible to have double
buffering be normal and single buffering be an auxilary window. 

If it isn't possible with the widget is it possible to have two normal
plane windows in the GLXconfig, and somehow get GLXgetconfig to do
the right thing?

Or is there yet another pathway to do this?

Thanks.

Mark.
