Just out of curiosity: is there any gain in avoiding the GL

conversion code?
As I said in my reply to Jose on the 00/20 patch, we would like to
eventually move the format conversion stuff to a common helper library
that can be shared by mesa main and the gallium code. If we are going
to do that, then we don't want any GL dependencies.
Yes, I know, I was just wondering why Mesa and Gallium would need/want
to avoid the GL dependencies in that helper library, since clients of
that library would usually be things like glTexImage or glReadPixels and
these deal with GL types.
Since OpenGL is only one out of many APIs provided by state trackers on
top of Gallium (some of which have nothing to do with OpenGL), code
below the Gallium interface using GL types directly is a layering violation.
