TSdlPenMotionEvent

Pressure-sensitive pen motion event structure (Event.PenMotion.* )

Depending on the hardware, you may get motion events when the pen is not touching a tablet, for tracking a pen even when it isn't drawing. You should listen for TSdlEventKind.PenDown and TSdlEventKind.PenUp events, or check TSdlPenInputFlags.Down in PenState to decide if a pen is "drawing" when dealing with pen motion.
