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.
