Yeah, you are right. This needs to be updated as well.

The implementation currently only supports mipmap levels for single-sampled 2D 
surfaces. Piglit on GEN6/7 currently fails on depth-stencil and multi-
dimensional formats. Seems we need to update Blorp's WM prog for this to work 
well. At that point, specifying LOD/level fields is not enough. I'm currently 
trying to figure out the best way to do this.
