* @summary Check if a JComboBox 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
* JComboBox 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 JWindow, JDialog and JFrame
* Expected Result: If TRANSLUCENT Translucency type is supported, the drop down
* should appear translucent.
