FeynGame 3.0

A major update of the program FeynGame is introduced. One of its main new functionalities is to visualize Feynman graphs generated by QGRAF. The QGRAF output can be either pasted into the FeynGame canvas for individual graphs, or the whole QGRAF output file can be processed. In addition, a number of new features and improvements have been implemented into FeynGame-3.0 in order to further facilitate the efficient drawing of Feynman diagrams in publication quality. FeynGame is freely available as jar or MacOS app file from https://web.physik.rwth-aachen.de/user/harlander/software/feyngame, and as source code from https://gitlab.com/feyngame/FeynGame.
