33 * Test Description: Check if TRANSLUCENT Translucency type is supported on the
34 *      current platform. Proceed if supported. Show a window which contains some
35 *      components and set with opacity less than 1.0. Another Window having a
36 *      canvas component drawn with an image can be used as the background for the
37 *      test window. Click on the components present in the window and check if
38 *      events trigger correctly.
39 * Expected Result: The components should trigger events correctly
