Description
Draws a polygon on drawable joining the specified points, using the current pen. Dashed lines start dashing at the starting point of the first segment.
If closed? is #t, then the polygon is closed, that is, a line is drawn from the last point in the sequence back to the first.
If filled? is #t then the polygon will be filled, using the current brush.
The function draw-polygon* is identical to draw-polygon, except that it passes composite objects, rather than separate coordinates, in its arguments. You should be aware that using this function may lead to a loss of performance.
