* @test
* @key headful
* @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)
