The attached allows the 50x30 polygon to be click-dragged anywhere within the polygon-- basically ds hotspots happen in a 10x10 quadrant within the polygon when an x/y pair is specified with a field variable, so I'm forcing hotspots for the entire polygon by spacing all field value coordinates no more than 10 pixels from each other. (You can overlay a simpler polygon if you want a cleaner-looking control surface.)
That's a lovely demo Jonathan. The small squares have their own esthetic. This approach is less hacky than my moving radiobuttons. Do you use it in practice, as GUI elements? It is very heavy on cpu.
