Everything drawing-related will be handled by the clients, which
then write the completed application image to a buffer which is
drawn as-is to the screen. There's no grabbing of pixmaps because
the client already has them.

Naturally, this should be handled pretty much seamlessly by the
toolkit used (gtk+, qt or whatever).

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
