  32  * @summary Check if a JComboBox present in a window set with opacity less than
  33  *          1.0 shows a translucent drop down
  34  * Test Description: Check if TRANSLUCENT translucency type is supported on the
  35  *      current platform. Proceed if supported. Show a window which contains an
  36  *      JComboBox and set with opacity less than 1.0. Another Window having a canvas
  37  *      component drawn with an image can be used as the background for the test
  38  *      window. Click on the ComboBox to show the drop down. Check if the drop down
  39  *      appears translucent. Repeat this for JWindow, JDialog and JFrame
  40  * Expected Result: If TRANSLUCENT Translucency type is supported, the drop down
  41  *      should appear translucent.
