Changeset 19395 for trunk/pswarp/src/pswarp.h

Message:

Fixed a bug in the tile transformation that was resulting in transformed data being overwritten with untransformed data (a single character bug --- 'y' instead of 'x'!). Attempted to make transformations a bit more efficient by only transforming the tiles that overlap the image; doesn't seem to make much difference.
