 * @summary Check if shaped, translucent and per-pixel translucent window is
 *          dragged and resized by mouse correctly.
 * Test Description: Check if PERPIXEL_TRANSLUCENT, TRANSLUCENT and
 *      PERPIXEL_TRANSPARENT translucency types are supported on the current
 *      platform. Proceed if they are supported. Create a window with some
 *      components in it, make window undecorated, apply shape in componentResized
 *      listener. The shape should match the window size; apply opacity of 0.7,
 *      apply translucent background of 0 and have a gradient painted as
 *      background from fully-transparent to fully-opaque in componentResized
 *      listener. Drag and resize the window using AWT Robot and verify that
 *      shape and translucency are correctly applied with pixels checking. Make
 *      the window appear on top of a known background. Repeat this for JWindow,
 *      JDialog, JFrame.
 * Expected Result: If PERPIXEL_TRANSLUCENT, TRANSLUCENT and PERPIXEL_TRANSPARENT
 *      translucency types are supported, the window should appear as specified
 *      with the expected shape and translucency. Window background should have
 *      translucent gradient in parts that are not clipped by shape, all the
 *      controls should be equally translucent.
