Is it possible/reasonable, in X version 10 or 11, to implement "memory
windows", that is, windows which have an associated pixmap which is
updated by graphical operations on the window (even the obscured areas)
and which handle exposure events by raster-oping from that pixmap?  Has
anyone already done this?
