The new PencilKit APIs allow to get stroke data from the user's drawing (PKStroke and PKStrokePoint). As far as I can tell though, the first time we can react to a new stroke is from within the canvasViewDrawingDidChange(_:) method of the PKCanvasViewDelegate. This method will get called *after* the stroke is finished.

Is there a way to react to the stroke *while* it is being drawn by the user? That would allow for a seamless reaction to the user's strokes.
