Whatever you implement needs to be something that at least *some* hardware
can support - which means that we should be using some of the existing
extensions rather than inventing new ones.

Also, if you stick with existing extensions, there is a better chance
that programs not specifically written for Mesa will take advantage
of this new code.  Note that Mesa is no longer the only game in town
for Linux users - the nVidia driver already has bump-map extensions - and
I fully intend my programs to make use of them.

You should be able to find out all about the nVidia extensions (for example)
at the www.opengl.org site.
