Synaptics Touchpad Sketch Utility

Tried drawing with the Synaptics touchpad; after all, there should be a way to map your finger's position to an absolute location in a window or on the screen. Found a little Synaptics Sketch utility for doodling, but it was pretty useless because it doesn't show your finger's position before you make a mark and you can only save your image in a proprietary "SKE" format. Oh, well.
