TSdlHintCallback

A callback used to send notifications of hint value changes.

This is called an initial time during SDL_AddHintCallback with the hint's current value, and then again each time the hint's value changes.

Remarks

This callback is fired from whatever thread is setting a new hint value. SDL holds a lock on the hint subsystem when calling this callback.
