// Revision 1.4  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 1.3  2004/04/15 10:31:29  botik32
// Interface change: added arc() function to surfacedriver.
//
// Revision 1.2  2004/04/14 14:58:17  botik32
// Changes to SGE driver's font handling to improve speed
// and usability.
// Changes in scrollableview,zoomablesurfaceview regarding
// debugging (added then removed) so this is a non-change.
//
// Revision 1.1.1.1  2004/03/26 10:50:26  botik32

// Demo now shows camera in the small window
// ScrollableView: added clear_surface() and update_surface()
//   functions
// GraphWindow: calls clear_surface() and update_surface() on update.
//
// Revision 1.6  2004/03/15 18:06:25  botik
// Activeleaf.cpp: removed bug causing problems with memory
// Context.cpp: added include of assert.h
