 * @test
 * @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 0.5. 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 with the translucency. Only window background
 *      should be translucent, all the controls should be opaque.
