I've done something like this.  The easiest way is to forget about XView
colormap segments and use X11 colormaps directly.  What I do is allocate
a private map with XCreateColormap and then copy values from the default
colormap into it.  You can associate the new colormap with a window by
reading the windows XID and using it in an appropriate Xlib function
(eg. XSetWMColormapWindows).
