<pre>Note that Gen4-5 don't expose GLSL 1.30, so many of Glamor's integer code paths
will be disabled (as GLSL 1.10-1.20 allow integers to be represented as floats,
so e.g. bitfield tricks may not work).
Gen4-5 of course use real integers, so we really ought to find a way to get
Glamor using integer paths properly. I believe those paths are faster, as well
as better tested. Ian has a couple of GL_MESA_* extensions in progress we
might be able to leverage...
(I don't know that this is actually the problem, it's just a difference between
Gen4-5 and Gen6+ that could be relevant. We'll have to look into it properly.)</pre>
