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.
