/* @public
*
* @brief Driver callbacks for getting notified on several damage calls
*
* The pointer to this struct can be obtained via DamageGetScreenFuncs().
* Drivers can inject themselves here, in order to get notified on
* DamageCreate(), DamageRegister(), DamageUnregister(), DamageDestroy().
*
* The fields may be assigned to NULL, if no action at all is wanted.
* (by default assigned to default implementations)
*
* This should ONLY be touched by video drivers, nobody else.
*
* So far the only one using it is the proprietary NVidia driver.
