getBoundingBox

If there are touch sequences being currently handled by @gesture, returns true and fills in @rect with the bounding box containing all active touches.

Otherwise, false will be returned.

Note: This function will yield unexpected results on touchpad gestures. Since there is no correlation between physical and pixel distances, these will look as if constrained in an infinitely small area, @rect width and height will thus be 0 regardless of the number of touchpoints.
