if you resize a 123
456
789 grid to the gesture (eg .. Z.. size 120x80 pixel) , the gesture goes through the fields 1235789. We need a function that tracks the "mouse pointer" and adjusts the grid in the screen. I have a simple mouse pointer application where you could test the success.

The alternative would be look into hd-home.c and figure out, how to disable data handling there and hook up the above instead.
