<pre>I can confirm this on Sandybridge. (It appears to work on Ivybridge, which is
strange...)
Apparently, the other thing the deleted code did was override LUMINANCE and
INTENSITY floating point formats to RED.
The failing case appears to be a L32_FLOAT -> R32_FLOAT blit. I don't
understand why that should matter...sampling from L32 will return <R, R, R, 1>
and writing to a single channel R32 render target ought to ignore the other
channels...
I'll keep looking.</pre>
