<pre>Reversing the mutual order of intel_blit_framebuffer_with_blitter() and
_mesa_meta_BlitFramebuffer() in i965-driver callback for blits fixes the said
newly introduced errors. This setup uses the blitter whenever possible and then
in cases not handled by the blitter prefers glsl-based blit over the software
path which looks to introduce its own set of failures.
With this setup on SKL the original failure of interest manifests itself after
a few testing rounds. On IVB in turn I cannot see failures in the original
piglit test or in my reduced version of it.</pre>
