I don't understand (2) and (1) of course is no more an issue with an 
external program than it is with a POV-Ray patch.

No, please reread the past postings in this concern.  The proposal to 
work on the unix specific part of the 3.5 code did only involve the X11 
display code.  This is exactly as it is in 3.5 and the changes you made 
there could be merged with the 3.6 code without any trouble.
