* @summary Check if a Choice present in a window set with opacity less than 1.0
* shows a translucent drop down
*
* Test Description: Check if TRANSLUCENT Translucency type is supported on the
* current platform. Proceed if supported. Show a window which contains an
* awt Choice 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 ComboBox to show the drop down. Check if
* the drop down appears translucent. Repeat this for Window, Dialog and
* Frame.
* Expected Result: If TRANSLUCENT Translucency type is supported, the drop down
* should appear translucent.
