------- Additional Comments from Tim Horton <thorton at apple.com>
an initial cut. currently we don't re-use existing tiles when bringing in
unparented views, because we can't tell if they've been purged without
parenting them, and don't want to cause a sudden surge in backing store if many
thumbnail views are made from unparented views at once, but this can be
revisited.
