Merge to M53: Account for video rotation in OnVideoNaturalSizeChange()

Merge to M53: Account for video rotation in OnVideoNaturalSizeChange()

This was always wrong, but now that natural size chages are always
emitted (commit 810dee4b15363fc5e1af55880afe79ebf5a1ebda) they are
causing all non-square rotated videos to render with the wrong
aspect ratio.

This CL ensures that sizes are treated the same way on this path as
in OnMetadata().
