I want to disable the zoom function

[jpyo0613]

I want to disable the zoom function
and a listener that can know the beginning and end of drawing.

like..

canvas.rasmContext.addDrawingChangeListener(DrawingChangeListener() {
    @Override
        fun onTouchStart() {
            
        }

            @Override
        fun onTouchEnd() {
            
        }

(option)
    @Override
        public void onDrawingChange(float x, float y) {
            
        }
})

Thank you for sharing this very well-made library 👍
