Instead of using the "proper" DamageDamageRegion for reporting the
first (virtual) damage in ProcDamageCreate that covers the borderClip
of the drawable window, use a new function DamageInitialReport that
uses damageReportDamage to do the work. This avoids sending all other
damage listeners a full window update when a new damage object is
created.
