Possible fix

The attached patch fixes the issue with shadowtex for me. Sven, can you try it and also see if doom3 is still OK with it ?

With 3 pipes values are NPOT, so align() is not suitable in some places I think.

Cool! This does indeed fix things!

The only remaining app with HiZ problems here is Lightsmark, but it seems to be a general problem tracked in bug 33648.
