That's what the angle command is supposed to do. Rotate distorts and is 
irreversable. There's documentation about it in the dictionary under the 
"rotate" entry. There's a discussion there about the resizing issue and 
how a rotated image fills its frame also.

I haven't had time to experiment, so I'm just being theoretical here. 
But if changing the angle is introducing distortion then it sounds like 
a bug (except that some distortion will happen regardless just because 
of how pixels work.) If the original rotation was done with the rotate 
command, then it is acting as expected and each successive rotation will 
distort the image further.
