FWIW, my Ada bindings already have some extra palettes plus the  
ability to switch black and white. I  hope to write Ada versions of  
the PLplot examples (I assume that's a prerequisite) and see what is  
involved with getting this work included with the official release. I  
think there might be a documentation project for the thick binding,  
but the standard PLplot docs should be good for the thin binding.
