Civ4 screenshot with fbo for offscreen rendering

Wine uses framebuffer objects to handle offscreen rendering by default, this
isn't working so well:

For example, in Civilization IV it results in character portraits rendering
garbage (see attached screenshot).

For some games and apps, this can be worked around by using "backbuffer"
instead, as documented in http://wiki.winehq.org/UsefulRegistryKeys but it
isn't working everywhere, and I wouldn't be surprised if this option was
removed in the future.

This might be a more general problem with Mesa instead of something specific to
radeon.

Please apply attached patch on mesa and provide me with full output when game
is started with RADEON_DEBUG=tex env variable.

Please attach glxinfo output too.

Oh, I see you're using r300g. Unfortunately I won't be able to help you since
don't know r300g that much. Maybe Marek Olsak will do.

Argh, I thought I mentioned r300g in my first message, sorry about that.

Interesting, it does seem to be working fine with r300c.

Yes, tried it when you first posted it on mesa-dev, it's working fine here! :)
