Summary Add DamageRectangleThreshold preference to tune the damage-rectangle merge limit

When damage tracking records many small dirty rectangles, the Damage class merges them into a coarser set once a maximum is reached, to bound bookkeeping cost. Until now that maximum was hardcoded to 4 in every consumer. This patch adds a DamageRectangleThreshold preference (default 4) so the limit can be tuned at runtime.
