So push them further down in the drawpixels cases so that we can switch over to Map/UnmapRenderbuffer() step by step.

It passes now. Bisect shows it is fixed by following commit. commit e1f9820b47e3f124c49cd2ab4e09328e0cc3e638 Author: Chad Versace Date: Thu Jan 26 11:01:36 2012 -0800 i965: Rewrite the HiZ op This is a combination of 4 commits.
