 * @bug 8032644

 * @summary Check if a per-pixel translucent window is dragged and resized by

 *          mouse correctly

 * Test Description: Check if PERPIXEL_TRANSLUCENT translucency type is supported

 *      on the current platform. Proceed if they are supported. Create a window

 *      with some components in it, make window undecorated, 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 JWindow, JDialog, JFrame.

 * Expected Result: If PERPIXEL_TRANSLUCENT translucency type is supported,

 *      the window should appear as specified with the translucency. Only window

 *      background should be translucent, all the controls should be opaque.
