	If the patch (or mesh...) is flat (as is the case for your
curtain), POV can't distinguish the inside from the outside,
so CSG intersection and differences are impossible. But you
can always cut holes in a patch object with clipped_by...
	If the patch is a closed solid, MegaPOV is able to do CSG
with it (albeit probably with a warning saying that it
doesn't work, although it does. There was such a warning in
uvpov, I don't know if it was removed)
