<li>NEW: stacked barcharts may have a small separation (default 1pt)</li>
<li>NEW: autoscaling for barcharts works now, also when stacked and unstacked charts are combined in one plot</li>
<li>NEW: JKQTPGeoBezierCurve for drawing bezier curves of degree 1-4 (+example \ref JKQTPlotterGeometricBezier)</li>
