+ * Test case for JME issue #1798: filtered scenes are squeezed by resizable
+ * windows.
+ * <p>
+ * If successful, a cartoon monkey head will be shown, and resizing the window
+ * (using the system's window manager) will not change its shape.
+ * <p>
+ * If unsuccessful, then making the window taller will make the head taller, and
+ * making the window wider will make the head wider.
+ * <p>
