// - By using "set_default_size(0,0)" in prefidalog.cpp we tell the window to shrink as much as possible,
// however this can result in a much to narrow dialog instead and much unnecessary wrapping
// - Here we set a lower limit of GUI_MAX_LINE_LENGTH characters per line that long texts will always use
// This means texts can not shrink anymore (they can still grow, though) and it's also necessary
// to prevent https://bugzilla.gnome.org/show_bug.cgi?id=773572
