True. It's a fix for DRI3 for either UXA or "none". Mesa allocates a
single page for a 1x1 texture, but this code thinks that should take two
pages causing a texture-to-pixmap operation to fail.

In particular, gnome-shell fails without this patch.

It's useful independent of this series, which is why I stuck it first.
