The latest build of the game Torchlight segfaults on start with Mesa 9.0 or git
master. The crash happens in  BlitNtoNCopyAlpha () in SDL2, but only if the
game is set to launch full-screen.

I tried reverting this on master but it seems dependent on other changes, so it
doesn't build. OTOH, the commit immediately prior to this one,
74027a9ba250f07a77ee40e105c50c27e4fc3bc0 is working so it's probably the right

I'm not sure if this is a driver problem or a bug in SDL, considering that
earlier builds of the game worked fine with Mesa 9.0.
