45d6ef373b bugfix: JKQTMathText: \sum and \prod used the wrong symbol in XITS-mode 
NEW: JKQTMathText: \limits and \nolimits work as in LaTeX now (before it was simply removed and the functionality implemented for a fixed list of symbols)
remove/breaking: JKQTMathText: \v[a-zA-Z] and shorthand for \vec{a-zA-Z} was removed
improvement: improved typesetting of sub-/supercripts, especially for large math operators and braces

279ef7880a - improved: geometric objects now use an adaptive drawing algorithm to represent curves (before e.g. ellipses were always separated into a fixed number of line-segments) 
- improved: constructors and access functions for several geometric objects (e.g. more constructors, additional functions to retrieve parameters in diferent forms, iterators for polygons, ...)
- 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

a67975e680 - major rework of graph styling (now using mix-in classes) 
- some reorganizations into different files
- additional options for graph filling (color gradients, textures, ...) as provided by QBrush
- PREPARATIONS: added a general feature to JKQTPPlotElement which allows to show a graph in a highlighted state (if supported by the derived graph class!)
- JKQTPXYParametrizedScatterGraph: added functors to transform column values into symbol type+size and line-width to give even more control
- JKQTPStepHorizontalGraph has been renamed to JKQTPSpecialLineHorizontalGraph (vertical variants also) and have gained additional features (baseline for filling and drawing of symbols)
- filled curve graphs (e.g. JKQTPSpecialLineHorizontalGraph) are now merely a specializedly initialized JKQTPSpecialLineHorizontalGraph

- new: added debugging option, which surrounds different regions with visible rectangles (JKQTBasePlotter::enableDebugShowRegionBoxes() )
- fixed: colorbars at top were positioned over the plot label
- new: frames (plot viewport, key/legend ...) may be rounded off at the corners
- new: diverse new styling options (default font name/size ...)
- speed improvements to JKQTMathText::useSTIX()
