[Bug 22684] Jedi Knight: Dark Forces II screen flips when picking up an item

The issue is read_from_framebuffer_texture which doesn't flip the front buffer
contents on read back. There is a comment as well which mentions that this
specific case should be avoided and that it is unimplemented. I should think
what should be done about it. The fun is that FBOs are useless (we need a RGBA
-> A download).

I'm not sure how I should fix it yet. In case of hw accelerated 8-bit
conversion the only thing really needed is a palette refresh. The whole
download step is not really needed assuming the texture is up to date
(apparently it isn't else this issue wouldn't be around).
