  30  * @summary Check if shaped and per-pixel translucent window is dragged and
  31  *          resized by mouse correctly.
  32  * Test Description: Check if PERPIXEL_TRANSLUCENT and PERPIXEL_TRANSPARENT
  33  *      translucency types are supported on the current platform. Proceed if
  34  *      they are supported. Create a window with some components in it, make
  35  *      window undecorated, apply shape in componentResized listener. The shape
  36  *      should match the window size; apply translucent background of 0 and have
  37  *      a gradient painted as background from fully-transparent to fully-opaque
  38  *      in componentResized listener. Drag and resize the window using AWT Robot
  39  *      and verify that shape and translucency are correctly applied with pixels
  40  *      checking. Make the window appear on top of a known background. Repeat
  41  *      this for JWindow, JDialog, JFrame.
  42  * Expected Result: If PERPIXEL_TRANSLUCENT and PERPIXEL_TRANSPARENT translucency
  43  *      types are supported, the window should appear as specified with the
  44  *      expected shape and translucency. Window background should have
  45  *      translucent gradient in parts that are not clipped by shape, all the
  46  *      controls should be opaque.
