Author: Eric Anholt <[email protected]> Date: Tue Jan 17 11:28:56 2012 -0800 i965/gen7: Set up surface horizontal alignment field. This is required for Z16 support for texturing, which is the first thing to have a horizontal alignment of 8. Renderbuffers don't need it, since they're always set up as the only mip level, but do it for completeness anyway. NOTE: This is a candidate for the 8.0 branch.
