 		Contains mouse and pen motion information. Supports relative, absolute positions and speed. See [method Node._input].
+		[b]Note:[/b] By default, this event is only emitted once per frame rendered at most. If you need more precise input reporting, call [method Input.set_use_accumulated_input] with [code]false[/code] to make events emitted as often as possible. If you use InputEventMouseMotion to draw lines, consider implementing [url=https://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm]Bresenham's line algorithm[/url] as well to avoid visible gaps in lines if the user is moving the mouse quickly.
