+system, since wxFont uses a reference counting system for efficiency.
Although all remaining fonts are deleted when the application exits,
the application should try to clean up all fonts itself. This is because
wxWindows cannot know if a pointer to the font object is stored in an
application data structure, and there is a risk of double deletion.
