I don't think there is any explicit wording in the protocol spec, but it was
intended that servers be allowed to convert RGB values into their hardware
range, and convert them back for QueryColors.  So, what you are doing is OK,
except that you (and we :-) should really be scaling values rather than
masking/shifting.  You notice this right away when you save away a color image
and then try and redisplay it using a standard colormap.  It's on our list of
things to fix in the sample server.
