That is probably the key: Poly_2d allows one to give the size of the
output image as parameters, but ROT does not take advantage of this
option. I added an OUTDIM keyword to rot.pro that lets one pass the
output dimension to Poly_2d. My copy is at

ftp://idlastro.gsfc.nasa.gov/landsman/idl/rot.pro

I suppose a possible additional keyword to rot.pro would be to let it
compute itself the size needed to preserve all the data, and create an
output file with that size.
