Bug detailed description:

It fails on Ironlake and Sandybrisge with mesa master branch, works well on 10.1 branch, spec_EXT_texture_array_copyteximage_1D_ARRAY and spec_EXT_texture_array_copyteximage_2D_ARRAY also fail with same bisect commit.

Bisect shows: 234db609 is the first bad commit. commit 234db609 Author: Eric Anholt eric@anholt.net AuthorDate: Fri Feb 28 13:23:25 2014 -0800 Commit: Eric Anholt eric@anholt.net CommitDate: Tue Apr 15 14:34:22 2014 -0700

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.
