 * @bug 8144735 8164811
 * @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.
