 * @summary Check if a window set with shape clips the contents
 * Test Description: Check if PERPIXEL_TRANSPARENT translucency type is supported
 *      by the current platform. Proceed if it is supported. Apply different types
 *      of shapes on a Window which contains some awt components. Shape should be
 *      applied in such a way that some components are partially clipped off. Check
 *      if the components appear only partially and events work correctly for those
 *      components - i.e. events occur only on the areas which appear and do not
 *      occur on the clipped off areas. Events should be checked by clicking on the
 *      visible and clipped regions. Repeat this for Window, Dialog and Frame.
 * Expected Result: If PERPIXEL_TRANSPARENT translucency type is supported, clicking
 *      on clipped region should deliver the event to the background (it should be
 *      another Window behind the test window)
