Have you looked at my demonstration of a full-screen magnifier
application called 'diopter' in /cvs/xapps on freedesktop.org?  I built
this as a demonstration for the FSG accessibility workshop last January
in Hawaii.

It shows a full-screen magnifier that passes input to the underlying
windows using an updated version of the Shape extension.
