PIGLIT: {'result': 'fail' }
234db609544ee521458ce8b648e70cffe2fda6f9 is the first bad commit
commit 234db609544ee521458ce8b648e70cffe2fda6f9
Author: Eric Anholt <<a href="mailto:eric@anholt.net">eric@anholt.net</a>>

meta: Add an accelerated glCopyTexSubImage using glBlitFramebuffer.
You'll note from the previous commits that there's something of a loop
here: You call CTSI, which calls BlitFB, then if things go wrong that
falls back to CTSI. As a result, meta CTSI reaches over into blitfb to
tell it "no, don't try that fallback".
v2: Drop the _mesa_update_state(), which was only necessary due to use of
_mesa_clip_blit() in _mesa_meta_BlitFramebuffer() in another patch
series.
v3: Drop an _EXT suffix I copy-and-pasted.
