	* java/awt/GraphicsEnvironment.java
	(localGraphicsEnvironment): New field.
	(getLocalGraphicsEnvironment): Added support for java.awt.graphicsenv
	property.
	(isHeadless): Added support for java.awt.headless property.
	(isHeadlessInstance): Call headless().

	* 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.
