 * @test
 * @key headful
 * @summary Check if dynamically shaped window is moved and resized by
 *          API correctly.
 *
 * Test Description: Check if PERPIXEL_TRANSPARENT translucency type is
 *      supported on the current platform. Proceed if it is supported. Create
 *      a window and apply shape in componentResized listener. The shape should
 *      match the window size. Drag and resize the window using API and verify
 *      that shape is correctly applied both with pixels checking and clicks.
 *      Make the window appear on top of a known background. Repeat this for
 *      Window, Dialog, Frame.
 * Expected Result: If PERPIXEL_TRANSPARENT translucency type is supported, the
 *      window should appear with the expected shape. Clicks should come to visible
 *      parts of shaped window only and to background for clipped parts.
