* Changes (from 28-Jun-2001)
* --------------------------
* 28-Jun-2001 : Integrated buffering code contributed by S???ren
* Caspersen (DG);
* 18-Sep-2001 : Updated header and fixed DOS encoding problem (DG);
* 22-Nov-2001 : Added scaling to improve display of charts in small sizes (DG);
* 26-Nov-2001 : Added property editing, saving and printing (DG);
* 11-Dec-2001 : Transferred saveChartAsPNG method to new ChartUtilities
* class (DG);
* 13-Dec-2001 : Added tooltips (DG);
* 16-Jan-2002 : Added an optional crosshair, based on the implementation by
* Jonathan Nash. Renamed the tooltips class (DG);
* 23-Jan-2002 : Implemented zooming based on code by Hans-Jurgen Greiner (DG);
* 05-Feb-2002 : Improved tooltips setup. Renamed method attemptSaveAs()
* --> doSaveAs() and made it public rather than private (DG);

* 22-Nov-2002 : Added test in zoom method for inverted axes, supplied by
* David M O'Donnell (DG);
* 14-Jan-2003 : Implemented ChartProgressListener interface (DG);
