POV-Ray already uses a kind of (proprietary) message-passing interface 
to transfer data between the "front-end" (which evaluates the command 
line and INI file, and also assembles the final image from the computed 
pixel data) and the "back-end" (which parses the scene file and does the 
actual computations).

In the back-end, the image size options from command line and INI file 
are evaluated in View::StartRender(), which is defined in 
source/backend/scene/view.cpp.
