<pre>Previously, the Meta CopyTexSubImage path would do ReadPixels and TexImage.
The TexImage was done via CPU mappings.
With this patch, it uses Meta BlitFramebuffer, which does texturing and
rendering. Unfortunately, it hits a limitation in our Gen4-6 rendering path:
the hardware ignores the low bits of the surface tile offsets. So, we get bad
rendering.
Jordan's gen6-layered series fixes this on Sandybridge. Thus, reassigning to
him. I'm not sure what to do about Ironlake.</pre>
