Dave Hoover 9733142d35 It's not a perfect solution, but make it so we can call the tile trimming task and
not actually write out new image to a file if we don't need to. 

This cuts my tileset building from 42 seconds to 22 when no files have changed 
(as opposed to 4 when it was skipping it altogether, but winding up with a hosed 
tsbundles.dat), so it's at least a decent bit better.
