There's no official extension to do that. And XEvIE has been broken for 
years and was removed a couple weeks ago from master. Besides, it didn't 
do what you want.

Compiz folks had Xserver patches to add mesh-type OpenGL-like transforms 
to windows. Don't know what state those patches are in...

Metisse (shameless plug) has working input-redirection but it requires 
an additional X server process.

Both approaches have their advantages and shortcomings, pick your poison. :)
