Destructor.
+See \helpref{reference-counted object destruction}{refcountdestruct} for more info.
\wxheading{Remarks}
-The destructor may not delete the underlying pen object of the native windowing
-system, since wxBrush uses a reference counting system for efficiency.
-
Although all remaining pens are deleted when the application exits,
the application should try to clean up all pens itself. This is because
wxWidgets cannot know if a pointer to the pen object is stored in an
