 * @test

 * @summary Check if a translucent shaped window trigger events correctly.

 *

 * Test Description: Check if TRANSLUCENT and PERPIXEL_TRANSPARENT traslucency

 *      types are supported on the current platform. Proceed if both are

 *      supported. Create a window with some components in it and a shape

 *      applied. Apply the shape such that some components are partially

 *      clipped. Set an opacity value less than 1. Check if the components

 *      behave correctly on mouse and key events. Do this test for awt Window.

 * Expected Result: Mouse and key events must work correctly. Only that portion

 *      of a component within the shape should trigger events. Key events

 *      should be tested for focus events and TextField/TextArea.
