/**
 * A test application for R2GizmoDrawers.  Since the drawers
 * only use information that is universal to all gizmos, they
 * can be tested without implementations of actual gizmos.
 * BallGizmo has been chosen as the stub AbstractGizmo for
 * availability reasons.  The test attempts to draw various
 * gizmos on a test context.<p>
 * 
 * EDIT: Since more gizmos have been completed, the test can
 * now make gizmos and will not have to resort to using a
 * BallGizmo as a stub.  However, existing test cases may be
 * grandfathered in.<p>
