one way of looking at it.  :-)

I think POV-Ray does not "do" X at all, the last version (I have access to)
which does is 3.6.1.  from 3.7.x it uses the SDL instead.  a real pity because
if POV-Ray output to an actual X window, knocking up front-ends a la 'qtpovray'
would be  doable in a(ny) number of (scripting) languages, with a single
supporting command line switch (cf 'xterm -into $id').

(also, why SDL in the first place?  all the joystick and audio etc facilities,
unused.  yet, no preview without)

not all Linux distributions go to lengths to disenfranchise their users.  ;-)
