Ah no.  gslib will only depth cue polys to black (I think).  So a faded
out poly would look really strange against a red background.  (if you
see what I mean)


LibGs will depth cue polygons/TMDs to ANY specified colour.

GsFOGPARAM has members rfc, gfc, bfc: basically the rgb members of the fog
colour.
By setting rgb, you can make libgs depth cue to any background colour.
In practice, black is mosty commonly chosen, but white generates a nice
misty effect.
