Well, I guess if it really doesn't work with pretty much any driver, you might
need to do that even if what you do is fully legal. I'd fix it for the radeon
drivers but I currently can't quite see how you'd notice the other contexts
upon a drawable change, as the __DRIdrawablePrivate struct only has a pointer to
a single context. Calling glXMakeCurrent in the drawing loops should work around
that problem (as that should make sure the hw buffer offsets get updated, just
as putting glDrawBuffers(GL_BACK) in there does), though again I don't think
this is needed by the spec.
