 * @summary Check if components present in a window set with opacity less than 1.0

 *          triggers events correctly

 *

 * Test Description: Check if TRANSLUCENT Translucency type is supported on the

 *      current platform. Proceed if supported. Show a window which contains some

 *      components and set with opacity less than 1.0. Another Window having a

 *      canvas component drawn with an image can be used as the background for the

 *      test window. Click on the components present in the window and check if

 *      events trigger correctly.

 * Expected Result: The components should trigger events correctly
