I need to translate some geometric objects and discovered that only a
few provide the plus/minus operators for translation. However, it
seems like a trivial job to add or subtract an (x,y) pair from any
geometric object since they are all based on a series of points. I
don't mind working on the code, but I cannot seem to find out where
the code is.
Can anyone give me a little guidance on what files to modify (and
whether there are any tricks to integrating it) so that I can expand
the range of geometric objects that can be translated?
Thanks for your help.
