| * @summary Check if a per-pixel translucent window shows only the area having |
| * opaque pixels |
| * Test Description: Check if PERPIXEL_TRANSLUCENT Translucency type is supported |
| * on the current platform. Proceed if it is supported. Create a swing window |
| * with some swing components in it and a transparent background (alpha 0.0). |
| * Bring this window on top of a known background. Do this test for JFrame, |
| * JWindow and JDialog |
| * Expected Result: Only the components present in the window must be shown. Other |
| * areas of the window must be transparent so that the background shows |
