I'm writing some X code that draws pictures in a moderate number of colors,
most often six or eight.  I realize that every X server is different, but
are there any rules of thumb that say whether I'm better off making eight
GCs for my eight colors, or using one GC and changing its colors with
XSetForeground and XSetBackground?

Both efficiency and style arguments would be interesting.
