I'm not sad about it.
It's great that there's a whole include file that reliably implements
quaternions.
It's not copyrighted.
It's all in SDL, so it can be experimented with by anyone, and any code written
in c++ to provide source-level capability can be checked against the extant SDL.

I'm nominating this as a file to be put on the wiki as a special resource.
If TOK or someone with knowledge of the use of quaternions can look it over to
determine if there are any other functions/macros that would be needed for a
more complete quaternion library, that would be great.

It would also be nice of someone could rewrite the macros as functions so that
they can be used at render time.
