<pre>From the ARB_texture_buffer_object extension spec:
While buffer textures can be substantially larger than equivalent
one-dimensional textures; the maximum texture size supported for buffer
textures in the initial implementation of this extension is 2^27 texels,
versus 2^13 (8192) texels for otherwise equivalent one-dimensional
textures. [...]
There's a bug in i965, that allows the creation of buffer surface states with
sizes greater than 2^27 texels when doing image load/store operations on
texture buffers. This patch fixes the issue:
<a href="https://patchwork.freedesktop.org/patch/211341/">https://patchwork.freedesktop.org/patch/211341/</a>
There doesn't seem to be any piglit tests which exercise this path. We should
create one to prevent this bug from showing up again.</pre>
