  actually, I don't think there is anything specific about using 16 colors.  I 
think it was just that 16 colors were used - it could very well be 12 or 25 - as 
far as X is concerned, it doesn't care (unless someone only had 4 bit color, but 
I don't know if such hardware ever existed).

  And right now, while only those 16 colors are used for standard drawing 
elements, hundreds of more are used for the actual images themselves.

  Private colormap is a leftover from 8 bit display - most 8 bit hardware could 
only display 256 different colors at a time, but out of the palette of 16 
million (24 bit color).  So one would use colormaps to determine what colors of 
the palette your are drawing.

  Now there may still be some people out there still on 8 bit color.  But it is 
probably fair to have 16+ bit color be a minimum requirement now days (actually, 
the other clients, that don't do color map stuff, will probably work on 8 bit 
color, just look pretty crappy)
