29  * @key headful
30  * @summary Check if a per-pixel translucent window is dragged and resized
31  *          by mouse correctly.
32  * Test Description: Check if PERPIXEL_TRANSLUCENT translucency type is supported
33  *      on the current platform. Proceed if they are supported. Create a window
34  *      with some components in it, make window undecorated, apply translucent
35  *      background of 0.5. Drag and resize the window using AWT Robot and verify
36  *      that translucency is correctly applied with pixels checking. Make the
37  *      window appear on top of a known background. Repeat this for JWindow,
38  *      JDialog, JFrame.
39  * Expected Result: If PERPIXEL_TRANSLUCENT translucency type is supported, the
40  *      window should appear with the translucency. Only window background
41  *      should be translucent, all the controls should be opaque.
