Hi,
I'm committing the attached patch that implements a primitive fullscreen
support on a peer independent level. Actually it does only resize and
relocate the fullscreen window. Peers that implement a real
(accelerated) fullscreen mode would override the setFullScreenWindow(),
getFullScreenWindow() and isFullScreenSupported() methods.
I wonder about the default of isFullScreenSupported in
java.awt.GraphicsDevice returning true. Does that make sense? Should it
be the other way, defaulting to false and requiring Devices that support
fullscreen to override it to return true?

* gnu/java/awt/peer/gtk/GdkScreenGraphicsDevice.java
(getDisplayMode): Added. Returns the current display mode.
(isFullScreenSupported): Added.
* java/awt/GraphicsDevice.java
(setFullScreenWindow): Implemented a primitive fullscreen mode.
This resizes and relocates the fullscreen window so that it uses
the whole screen. This is not a fully accelerated fullscreen
exclusive mode.
Best regards,
/Roman
