Everyone - 

Please help clarify for me. 

I was reading the ICCCM about Colormaps (4.1.8).  I'm trying to figure
out what to do if I need more room for colormap entries than is available
in the current colormap for a window.  From the ICCCM (and other sources)
it sounds like I'm supposed to do the following.

 1. Use XCopyColormapAndFree:

 2.  Then if all of my windows and subwindow share colormaps, use
     XChangeWindowAttributes
    
     Otherwise, use XChangeProperties to set the colormap.

     Both of these notify the window manager about a colormap change.
     
 3. Never use XInstallColormap. Leave that to the window manager. 
    But what about XSetStandardColormap? 
    What about XSetWindowColormap?

Basically, is XChangeWindowAttributes/XChangeProperties sufficient to 
"install" the new colormap? Is there any way to request that a new colormap
be installed for all of a client's windows without explicitly calling
XChangeWindowAttributes for each window?

Thanks for any info on this topic - Lisa
