I am wondering if it is possible to make a proc that will fill a single pixel on the map. For example, you would send the proc the turf you and the coordinates of the pixel within the turf, and it would turn on that pixel. Then you could use another proc to turn off the same pixel. I have seen demos which create icons and display them in the browser, and check to see what color a pixel is, but I haven't found any that deal with simply turning a pixel on and off. I know it would have to do with DrawBox, but I couldn't seem to get it to do what I wanted.
