- improved documentation - changed: using static const variables instead of \c #define for fixed default values (e.g. JKQTPImageTools::LUTSIZE, JKQTPImageTools::PALETTE_ICON_WIDTH, JKQTPlotterDrawinTools::ABS_MIN_LINEWIDTH, JKQTMathText::ABS_MIN_LINEWIDTH ...) - 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()
