Sorry if this has already been discussed. My knowledge of RPL is rapidly fading due to lack of use.

I just ran through a series of tests with this, using both absolute coordinates and user coordinates, and it seemed to always toggle 1 pixel in every test I did. I can't claim to have tested it exhaustively, but everything I tried seemed to confirm a single pixel being toggled.

That's actually a very efficient way to toggle a pixel. Great idea, Joe! I hate to think that your RPL days are behind you, though. That's bad news indeed.
