The thing is, the float equivalent of the format is RBGAF32.I don't mind RGBA128, but are there any other suggestions?
We have RGB48 (packed RGB 16:16:16, 48bpp) and RGBA64 (packed RGBA 16:16:16:16, 64bpp), so this new format can't be called RGBA32, lest we want to make things confusing. So make it RGBA128 for now, and if someone suggest something better then it can be considered.
