- Introduce Qt 5 signal-slot connection syntax.
- Merge MainWindow::createMenus()/createActions()
into MainWindow::createMenus(), removing the need
to store the actions as member variables.
Use QMenu::addAction() for brevity.
- For actions in QActionGroups, carry the Valuator enum
in QAction::data so that the slot to handle the selection
does not need to compare the QAction pointer itself.
- Use a non-modal QColorDialog, so that the user
can change colors more easily while drawing.
- Choose saner shortcut keys: control-Q should not
override the default usage for quitting the application,
and using shortcuts for About dialogs is anyway dubious.
- Improve the example documentation.
