29  * @summary Check if a per-pixel translucent window is dragged and resized by
30  *          mouse correctly
31  * Test Description: Check if PERPIXEL_TRANSLUCENT translucency type is supported
32  *      on the current platform. Proceed if they are supported. Create a window
33  *      with some components in it, make window undecorated, apply translucent
34  *      background of 0 and have a gradient painted as background from
35  *      fully-transparent to fully-opaque in componentResized listener. Drag and
36  *      resize the window using AWT Robot and verify that translucency is
37  *      correctly applied with pixels checking. Make the window appear on top of
38  *      a known background. Repeat this for JWindow, JDialog, JFrame.
39  * Expected Result: If PERPIXEL_TRANSLUCENT translucency type is supported,
40  *      the window should appear as specified with the translucency. Only window
41  *      background should be translucent, all the controls should be opaque.
