I fixed my version to not install color maps, and to instruct the window
manager to do it (I use twm right now).  However the colormap *STILL* doesn't
look right.  The qix is made of the colors allocated by the other clients,
half of which are black.  The code seems to make a HSB map for the qix but
I have never seen it.  Life and hop (the fractals) also seem to suffer from
an overabundance of black.  I am shure twm installs my colormap, I set the
ColormapChangeMask bit so I could get colormap notify events.  I recieve one
on the xlock window for the cmap that xlock creates, and I never see it get
uninstalled.  So something strange is up with colormaps, do I not only have
to tell twm to install my map, but that I changed it?  That doesn't seem
right...
