Subject:   -84- 1.0 Bug with two-sided material and pfMtlColorMode()
Date: 26 Oct 1993 00:00:01 EST

  Applying a back-sided material which had a color mode
  (pfMtlColorMode), would set the GL lmcolor mode. Since IrisGL does
  not support lmcolor for back-sided materials, this could have caused
  front-sided materials to use an improper lmcolor mode.
