I guess those hacks all pertain to POV-Ray 3.6 or earlier; the internal 
architecture has changed a lot from 3.6 to 3.7, and probably haven't 
made implementation of such a feature any easier.

I did an attempt at it a few months ago, but postponed any work on it 
due to the unexpected complexity of the task.
