Use the external scroll offsets provided by Gecko to:
(a) Offset primitives and clips by accumulated scroll offset.
(b) Adjust the scroll transforms and hit test results.

This allows primitives and clips to be stored in a true local space,
that is consistent between display lists, even if scrolling has
occurred. This is a step towards planned picture caching improvements.
