Thanks Chris.  As far as avoiding CLEAR operations, I'm not sure we have much
choice.  The RS274X file format has a "negative polarity" command, which pretty
much lets the user "erase" previously drawn objects by drawing a negative
object over them.  Since we allow transparency, I didn't see any other way than
to use the CLEAR operator to draw over it, since we can't just draw the object
using the background color.  Are there some other methods to achieve the same
effect?

Cheers--
Julian
