This isn't a performance issue. My code will have lower performance because it
is more complex than drawing a rectangle. The bug is that there are color
combinations that the current Rectangle() based code will not produce a clear
focus rectangle. My code duplicates the Microsoft method which ensures that a
clear focus rectangle will be drawn on any color combination no matter how bad
it actually looks.
