Sounds like fun. someone needs to go through this that isnt me. stared at it 
too long.
for instance, i'm sure i'm forcing alignment unnecissarily in a lot of places.
shooting wild, trying to eek out that last bit of performance. ;)

sounds like a plan to me. however, turning this into enough "small" patches 
to be useful might prove very painful. ;)

uhm, no, my situation is pretty hideous.

my input images are in tiff, but due to political reasons, i can only access 
the images as jpegs, at this point. converts all of them to PPMs. you can imagine what 
everything does to my precision. :/

i was just copying the functionality that was there. the origional program has 
hand-written PPM parsing library in it. i wanted something more modern. ;)
