	   Along a similar topic... The other reasonably common thing to
   want to do to displayed images is to alter their associated colormap
   to adjust image contrast or something more application specific. It
   would be nice if there was some level of CLIM's layered protocal which
   would allow you to do this type of thing without having to bypass CLIM 
   completely and interact directly with the native window system. 

Allegro CLIM has "layered" and "dynamic" colors, that do exactly this.
Sometime LispWorks CLIM will have this as well.

Genera CLIM is obviously not going to change much any more...
