+ * @key headful
+ * @summary Check if a per-pixel translucent and translucent window is dragged
+ *          and resized by mouse correctly
+ * Test Description: Check if PERPIXEL_TRANSLUCENT and TRANSLUCENT 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
+ *      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 translucency is correctly applied with pixels checking. Make
+ *      the window appear on top of a known background. Repeat this for specified
+ *      JWindow, JDialog, JFrame.
+ * Expected Result: If PERPIXEL_TRANSLUCENT and TRANSLUCENT translucency types
+ *      are supported, the window should appear as specified with the translucency.
+ *      Both window background and all the controls should be translucent but
+ *      background should have a gradient in translucency while controls - not.
