Polish charactermap example

- Use Qt 5 connection syntax.
- Introduce helper function to calculate the square size, remove
  the existing 24 pixel limitation since that makes it impossible
  to render 20pt fonts.
- Add filter chooser for font filters.
- Add menu and info dialog showing DPI and default fonts.
- Streamline code
