  I think that it uses the R and G values for the grayscale value (and leaves
B to 0), but I can't remember for sure.
  This mode is nowadays quite seldom needed and only usable by specialized
programs (usually HF-generation ones). Of course POV-Ray itself is one such
program, so there might be some use for it (even though less likely nowadays,
as we can create heightfields from any function...).
