What do those formats provide that other formats do not provide? Signedness,
or something else I missed?
Using GL_NV_texture shader and GL_ATI_envmap bumpmap is definitly the way to
go, but I am concerned about macos, where neither of those extensions exist.
But working around that issue will be tricky because the shaders depend more
on the stateblock then, and things get increasingly ugly.
Oh, and it seems that you have proven me wrong with my suspicion that sRGB
correction is the cause of that :-)
