Officially that would have been Thosten Fröhlich, but judging from the
change description he may just have merged other people's changes:

"Merged in photons, new light groups, more isosurface functions,
 "hat" token as exponent sign in express.cpp, lighting changes,
 normal bug fix and various other small fixes and extensions"
(Perforce change 237, 2000-06-26)

`u_steps` and `v_steps` already existed at that point.
