problem with fullscreen magnification using composite

[Carlos Eduardo Rodrigues Diógenes]

Hi,

I think, correct if I'm wrong, that with Deron modifications of the
composite extension, it's possible to acquire fullscreen magnification.

Attached is the test program that I write to try it, but what I'm
getting is infinite recursion of the magnified image. Someone can point
me what I'm doing wrong?

I'm running X11R7, compiled one day ago.

Thanks,
