/// Revision 1.3  2004/05/03 21:02:01  botik32
/// Significant changes and many bugfixes.
/// ScrollableView now has a background color used to
/// tell SurfaceDriver to clear with.
/// SurfaceDriver's clear() requires a color now
/// Added SceneEvents for all node additions/removals
/// in GroupNode and Camera.
/// Added paint_selected and paint_selected_invalid
/// to ActiveLeaf
/// Modified ActiveLeaf's mouse_down and mouse_up
/// handler signatures to accept an Event* instead of
/// Camera*
/// - Many more bugfixes
///
/// Revision 1.2  2004/04/20 08:55:51  botik32
/// Major interface change.
/// Added HUDView in Camera; switch_to_HUDmode for Camera
/// BaseSceneNode: internal implementation changes;
/// Major changes in HUDGroup behaviour
///
/// Revision 1.1.1.1  2004/03/26 10:50:24  botik32
/// Initial release

/// Revision 1.12  2003/11/24 20:45:29  botik
/// Merged four features from surfacecamera into camera.
/// Modified ScrollableView to hold a width/height of
/// the viewport and to report it to whoever asks.
/// Added scenex, sceney fields to Event.
/// Added coordinate transform for all messages, done
/// at camera level. This should speed up drawability
/// and mouseover checks.
///
/// Repaint and mouse detection work now over arbitrary
/// magnification.
/// Borderlayer is broken and scrolling segfaults in
/// a weird way.
///
/// Revision 1.11  2003/11/24 16:12:10  botik
/// Halfway through major redesign of a view's geometric
/// parameters. This will influence zooming and repainting.

/// Changed the way repaint works by using a screen
/// rectangle as intermediate event.
/// Added get_screenrect to Camera

///
/// Revision 1.9  2003/11/18 13:54:06  botik
/// Got the borderlayer to scroll well.
///
/// Revision 1.8  2003/11/17 23:38:45  botik
/// Fixed the framework to work with multiple cameras on
/// one window. There is a clear bug that does not clear

/// Changed scrolling to remove flicker when multiple
/// cameras are present on a window.
/// Scrolling is still slow.

/// Added handling of NodeTranslateMessage for LeafNode
///
/// Revision 1.6  2003/11/15 16:45:18  botik
/// Added ActiveLeaf node allowing for much easier scene
/// node creation.
/// Added default_cursor to scrollableview.
/// Numerous bugfixes.
/// MouseIn/Out now changes cursor.
