I don't think we have had issues when we didn't have this format before. Emulation might be tricky it is not as easy as emulating R32F we could just read back using GL_RED but there is no GL_RG without texture_rg. On the Nvidia side ARB_texture_rg is catching up quickly. A stable gl3 driver will be out within a short time.

I think we should emulate this format like we emulate R32F with ARGB32F if GL_TEXTURE_RG is not supported. It is a fairly new extension and the format is probably rather important.
(It should not be part of this patch though. Just a general note, the patch itself looks ok)
