Subclasses are encouraged to improve the quality of those hints by
filtering out mask bits which haven't *actually* changed since the
last notification. To do so, they would
- copy the hint (it's passed as a const),
- clear any irrelevant bits, and
- call this implementation on the way out
Good hinting logic is app-specific, and non-trivial to tune, but it's
worth doing, because it helps minimizes flicker for things like
toolbar button state.
