Not sure if I have anything to contribute. Just thinking, sounds like
you need small files and a way to use them with good enough quality.
How about loading them as image_maps in POV, outputing as much larger
files as a pre-process using interpolation/antialiasing then inputing
back in afterward un-interpolated. Like I say, unsure of the actual
results you would have in that particular case though. At least this way
you can start small and end big, using the POV output as a image
processor to smooth out the scaled up images/hf.
Understand?
