 * @summary Check if a window set with shape appears in the expected shape
 *
 * 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. Make it appear with a known background. Use
 *      get pixel color to check whether it appears as expected. Repeat this for
 *      Window, Dialog and Frame.
 * Expected Result: If PERPIXEL_TRANSPARENT Translucency type is supported, the
 *      window should appear with the expected shape.
