<pre>
    DrawPointList(sequence, pens=None)

    Where sequence is a tuple, list, whatever of 2 element tuples
    (x, y) and pens is either None, a single pen or a list of pens.

<pre>
    DrawLineList(sequence, pens=None)
</pre>
     Where sequence is a tuple, list, whatever of 4 element tuples
     (x1,y1, x2,y2) and pens is either None, a single pen or a list
     of pens.

<pre>
    DrawRectangleList(rectangles, pens=None, brushes=None)
