Large Image Export

Yes, the limitation is in snapshot, although there are other places
where we hit the same limit. When rendering an image via an InageView we
do the tiling correctly.
I haven't seen anything lower than 4K x 4X in practice, so that should
be safe. We do query and keep the max texture size internally in Prism
(per-resource-factory), but don't expose it via a public API.
