sorry for the typo, that's "gdalwarp"

My point was not that you could use it to find the pixels, but that you 
could use it to do the whole job. gdalwarp takes one image, and warps it 
to create a new image, which can be a different projection and, I think, 
a different resolution. If you use the "lanczons" method (which I think 
is anti-aliasing), you may get close to what you want.
