don't know how to do this choice when many type are available. I
think they are not equivalent depending on what you want to do. So
the easiest solution is to test them on each combination of patch
/ hardware.<br>

I support to have a real RGBA32 than only a RGB32 with only three
channels. It is more easy for me to mix textures from framebuffer in
shaders with a "real" alpha channel. That's why i often use RGBA for
this purpose (instead of RGB32)...<br>
