GLT is a library that evolved over several years of writing a lot
of OpenGL programs. It always seemed to me that there could/should
be a well standardised geometry library, but I wrote my own because
there wasn't much around at the time in 1996.
I don't think an OpenGL dependency should be introduced into Boost,
but I would imagine an OpenGL-oriented convenience layer could well
complement a boost geometry library. (As part of Boost, or not)
By reason to mention the GLT math stuff was to illustrate a set of
functionality that I think would be relevant to a boost geometry
library. There are things I would do differently to GLT (benefit
of experience), especially now that templates are much better
supported by various compilers.

Yes, quaternions too.
