* gnu/gcj/awt/ComponentDataBlitOp.java: New file.
* gnu/gcj/awt/GLightweightPeer.java: New file. * java/awt/BorderLayout.java: Implemented all methods. * java/awt/Button.java (actionListener, actionCommand): Renamed and modifier change.

(hashCode): New method. * java/awt/Component.java (visible, enabled, eventMask): Set defaults. (getGraphicsConfiguration): Delegate to getGraphicsConfigurationImpl(). (getGraphicsConfigurationImpl): New method. (getToolkit): Only return value from peer if not null. (isDisplayable): Check with parent. (isShowing): No parent implies not showing. (getForeground): Check parent property if local is null. (getBackground): Likewise. (getFont): Likewise. (setForeground): Inform peer. (setBackground): Likewise (setLocale): Invalidate component. (getColorModel): Implemented. (setLocation): Invalidate, or ignore if no change. (setSize): Invalidate, or ignore if no change. (setBounds): Invalidate, or ignore if no change. (isOpaque): By default, heavyweight implies opaque. (isLightweight): Implemented. (getMaximumSize): Implemented. (doLayout): Implemented, NOP. (validate): Implemented, NOP.

(addNotify): Allow container to notify children before event mask is set in peer. (addNotifyContainerChildren): New method. (removeNotify): Visibility should not change on removeNotify. (paramString): Implemented. (list): Implemented two of the list methods. * Container (myInsets): Removed, insets are managed by peer. (getInsets): Query peer. (addImpl): Fix reparenting, enable events for lightweights, initialize component array. (validate): Call doLayout in validateTree() instead. (validateTree): Do nothing if already valid. Call beginValidate(), endValidate() on peer. Call validateTree() instead of validate() for children that are containers. Mark valid after validation of children. (setFont): Partial implementation. (paint): Implemented. (visitChildren): New method. (visitChild): New method. (update): Implemented. (print): Implemented. (paintComponents): Implemented.
