Is there some reasonable way to rotate pictures.  I cannot find in
hints in IM.  I have seen programs that do it though.

All I can think of is drawing the picture into an offscreen bitmap,
converting all the coordinates to polar, adding the rotation, and
writing the new points into another bitmap.  This, unfourtunately, is
probably rather slow, and causes one to lose the PICT nature of the
picture: that is, I think it can then only be represented as a bitmap,
and thus will be larger than I might like.

Any canned packages to do this?  Any help would be appreciated.

					Appropriate Remarks,
							Lewis.
