 * @summary Check if translucent window is dragged and resized
 *          correctly.
 *
 * Test Description: Check if TRANSLUCENT translucency type is supported
 *      on the current platform. Proceed if they are supported. Create
 *      a window and apply opacity of 0.3. Drag and resize the window
 *      using AWT Robot and verify that translucency is not affected.
 *      Make the window appear on top of a known background. Repeat this
 *      for Window, Dialog, Frame.
 * Expected Result: If TRANSLUCENT translucency type is supported, the
 *      window should show the background. Dragging and resizing
 *      shouldn't affect the translucency.
