``` gui/mainwindow.cpp contains so many superflous/redundant include directives, that doxygen refrains from creating a visualization for this particular source file. Only after some manual squeezing can I reduce the _long_ list of includes to a bare

minimum. Doxygen's graph still is very wide, but at least accessible. ```
