If we considered PAL, at 720x576 at 25 fps, then we are looking at copying 
between 20 and 40 Meg to the screen per second, depending on the color depth 
of the screen.

However, if we were to copy data from the Cutter to the GUI, then the problems 
that arise are due to context-switching. We would have to consider looking at 
the Cutter as a seperate thread rather than as a seperate process.

I don't like the idea of threads for a number of reasons : Firstly, if the 
Cutter crashes, it will take the GUI with it. Secondly, we would still have 
to allow the Cutter to run as a seperate process so that it could be run 
remotely or for batch processing anyway. Thirdly, it would really screw up my 
idea of having a scheduler for multiple cutters distributed on multiiple 
computers ;-)

Cheers,
Jason
