I can use two separate channels, one color and one monochrome. I'm not very
familiar with the use of a pfColortable. Is it possible to map a RGBA color
texture to a monochrome texture using one? The man page suggests (to me at
least) that the table takes an intensity or color component value and maps
it to a color vector. I don't see how to use that to map a color texture to
a monochrome texture. What am I missing?
