I think maybe I decided copying was ok as long as:

Right, I keep forgetting about the issues involved with mixing X11 and
OpenGL. If we exclude the 3D window, it doesn't matter which buffer is
drawn to though, or am I missing something again?
It matters because then you'd only see the results when X and GL agree on
which one is the front buffer...
I don't see what difference it makes when the copy happens -- I think the
current shadow module implementation is fine for that.
For one, there can be no copy between to flips...
Oh yes, that's a good point.
