AbstractPointListShape
Renders a
PointList as a series of line segments. A Polyline figure should be
positioned by manipulating its points, NOT by calling
Figure.setBounds(Rectangle).
A polyline's bounds will be calculated automatically based on its PointList. The
bounds will be the smallest Rectangle large enough to render the line properly.
Children should not be added to a Polyline and will not affect the bounds calculation.
