docs: Draws a series of lines on the current :py:class:`Layer` with the current :py:class:`Brush`.
  		No interpolation is applied to these point and :py:meth:`drawLine` will be used to connect all the points lineraly.
  		Coordinates are relative to the original layer size WITHOUT downsampling applied.
  		
  		:param pointList: A list of point like :code:`[(0, 0), (100, 100), (100, 200)]`.
  		:rtype: Nothing.
