30 * @summary Check if a per-pixel translucent window is dragged and resized by
31 *          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 and have a gradient painted as background from
36 *      fully-transparent to fully-opaque in componentResized listener. Drag and
37 *      resize the window using AWT Robot and verify that translucency is
38 *      correctly applied with pixels checking. Make the window appear on top of
39 *      a known background. Repeat this for JWindow, JDialog, JFrame.
40 * Expected Result: If PERPIXEL_TRANSLUCENT translucency type is supported,
41 *      the window should appear as specified with the translucency. Only window
42 *      background should be translucent, all the controls should be opaque.
