   No, what this means is that a full range of Visuals will be available
to support the various hardware modes.  For example there will be a 24 bit
TrueColor visual on machines with 24 bit planes.  I think all SGI machines
use 8 bit DACs.  It seems silly to me to use anything more since I don't
believe the human eye is that sensitive.  Supposedly normal humans can only
see 6 bits, and some specially trained people like radiologists can see
8-10 bits gray scale.
