Some people here will beg to differ with you. :-)

Then again, with the exception of, say, large meshes, strictly *parsing*
a scene probably will always be fairly fast; it's the execution of SDL
loops and macros that gets hairy. However, Povray seems to consider that
as part of the "parsing" process.

FWIW, I've worked on scenes that took 10-15 seconds just to "parse" (due
to loops that procedurally generated lots and lots of objects).

You know you've been raytracing too long when you hear a name beginning
with the letter K and wonder if it's David Buck's middle name.
