GRAPH 3D v2.425 (20-FEB-2017)

[Han]

I have a version that includes touchscreen gestures, but done differently from how you did it. It's based on a generic key and touchscreen handler I wrote a long time ago (the skeleton is found in an article I wrote on programming the HP Prime). A few folks already emailed me about touchscreen gestures and I kept putting it off since it wasn't high on my priority list. However, if people are interested in using the touchscreen, I will put up another update once I test it more rigorously. You can then see how I implement it so that it also detects taps on the screen and keeps it separate from motion gestures.
