 * @test

 * @summary Check if dynamically setting a shape works

 *

 * Test Description: Check if PERPIXEL_TRANSPARENT Translucency type is supported

 *      by the current platform. Proceed if it is supported. Show a window which

 *      contains some components and apply a shape for the Window when the window

 *      is visible. 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 - ie, 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)
