ATI_fragment_shader fixes: fix bug in passTexCoord (caused by recent changes). Fix sampling from wrong texture unit. Apply swizzling before texture sampling, and hopefully get non-projected coordinates from swrast. (still does not work at all with sw doom3, way too dark just the same as with the doom3 arb2 path)
