                This test checks for setCursor in a JPanel when added to a
                JFrame's contentPane.

                1. Verify that the cursor in the left side of the test window
                    is a text cursor.
                2. Verify that the cursor changes to the crosshair cursor when
                    pointing over the button.
                3. Verify that the cursor changes to the hand cursor when in
                    the right side of the splitpane (and not on the button).
                4. Verify that the cursor changes to the wait cursor when in
                    the empty bottom section of the test window.

                If true, then pass the test. Otherwise, fail this test.
