Adam Barth f3c8503dfc Plumb resize notifications around sky/shell
This CL plumbs resize notifications from SkyView to Engine. I've taken the
opportunity to reorganize how notifications generated by SkyView are plumbed to
the GPU and UI threads. This approach should reduce the amount of plumbing
needed for new notifications.
