<li>improved: constructors and access functions for several geometric objects (e.g. more constructors, additional functions to retrieve parameters in diferent forms, iterators for polygons, ...)</li>
<li>improved/breaking change: reworked class hierarchy of parsed function plots and declared several setters as slots.</li>
<li>improved/breaking change: reworked class hierarchy of bar charts.</li>
<li>improved/breaking change: reworked class hierarchy of range charts.</li>
<li>improved/breaking change: reworked graph Base-Classes (promoted several setters to slots, added Q_PROPERTY- and Q_ENUM-declarations...)</li>
<li>improved/breaking change: made more functions and function parameters const</li>

<li>new: all geometric objects can either be drawn as graphic element (i.e. lines are straight line, even on non-linear axes), or as mathematical curve (i.e. on non-linear axes, lines become the appropriate curve representing the linear function, connecting the given start/end-points). The only exceptions are ellipses (and the derived arcs,pies,chords), which are always drawn as mathematical curves</li>
<li>new: a new graph class JKQTPXYFunctionLineGraph draws parametric 2D curves ( \f$ [x,y] = f(t) \f$ ), see \ref JKQTPlotterEvalCurves for an example</li>
<li>new: added several new copy/set-functions to JKQTPDatastore</li>
<li>new: added JPQTPlotter signal, when widget was resized</li>
<li>new: added JKQTPlotter signal, when widget was resized</li>
<li>new: added JKQTPFilledHorizontalRangeGraph, complementing JKQTPFilledVerticalRangeGraph</li>
