Indicates that the system supports full window transparency. Transparent windows will have only limited or no functionality on a platform that doesn't support it.

NOTE: Currently, this support is available on all platforms except Linux systems without the XComposite extension. The XShape extension is used in that case, so the window edges are aliased.

NOTE: In an environment with enabled security manager (for example in applet mode), usage of transparent windows is protected by security checks. If the application doesn't have the required permissions, it won't be able to use this feature and the system will appear as if the support for transparent windows wasn't implemented. This includes returning false from the Platform.isSupported(TRANSPARENT_WINDOW) test.
