Note that we can avoid all of the issues of "how does a window manager
handle topmost windows" if we introduce a new mode, such as, "take
this window and make it the priority window until I tell you otherwise
or destroy the window."  The priority window is defined to always be
on top of all other windows except screen saver windows. To implement
this concept we can leverage the screen saver implementation as
Keith suggested. This concept has virtually no visibility to window
managers at all; they don't need to worry about it.

This idea has the same simplicity and ease-of-implementation as the
topmost window concept but without any of the gnarly window manager
issues. Plus it is a feature which is associated with the composite
extension, which is good because it is mostly composite managers
that are going to want to use it.
