- 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
