Please don't write off PseudoColor quite yet. A writable color map is
a boon for those of us with complicated layered graphics to draw. It
greatly simplifies the maintenance of separate layers.

But for nearly all systems, allocating a new colormap for specific
windows creates color flashing when the windows change focus. When
there are enough color slots avilable in the default colormap,
XAllocColors (note the plural) gives a much more pleasing effect.
(Though, I just really noticed the the "million". That could indeed
change the balance.)
