	123	Some methods have been added to wxDC to help with optimization of
	124	drawing routines. Currently they are:
	125
	126	<pre>
	127	DrawPointList(sequence, pens=None)
	128	</pre>
	129	Where sequence is a tuple, list, whatever of 2 element tuples
	130	(x, y) and pens is either None, a single pen or a list of pens.
	131
	132	<pre>
	133	DrawLineList(sequence, pens=None)
	134	</pre>
	135	Where sequence is a tuple, list, whatever of 4 element tuples
	136	(x1,y1, x2,y2) andd pens is either None, a single pen or a list
	137	of pens.
