No significant changes have been made to the display routines of POV-Ray
for a long time.  Any display functions that have been written in the
last years (i'd say since version 3.1) will still work with current
POV-Ray (and in fact the SVGA code has not been modified since then.

Any modification of POV-Ray that is not part of the official version.

The purpose of a real time OS is to have detailed control of task run
times (and the ability to predict them).  This is rather pointless for a
program like POV-Ray since you do not even know how many CPU cycles a
render will take before actually rendering it.
