libGL diversions

[Cyril Brulebois]

Hi,

(adding debian-x@ and quoting in full for context, just in case somebody
there has something to say on this matter.)

Making it general, so non-nvidia, non-fglrx, is probably a good idea, if
you are both going to use it. /usr/lib/mesa indeed seems like a bad idea.
I guess mesa-diverted is self-explanatory enough.

Frankly, sorry, but I've already enough to do with free software.
