<warning>
To work with graphic objects HSLF uses Java2D classes
that may throw exceptions if graphical environment is not available. In case if graphical environment
is not available, you must tell Java that you are running in headless mode and
set the following system property: <code> java.awt.headless=true </code>
(either via <code>-Djava.awt.headless=true</code> startup parameter or via <code>System.setProperty("java.awt.headless", "true")</code>).
</warning>
<p>
When you add a shape, you usually specify the dimensions of the shape and the position
of the upper left corner of the bounding box for the shape relative to the upper left
