           Summary: Specifying align but not position behavior is not
                    intuitive
           Product: TextTracks CG

Consider specifying a cue an specifying just the align setting:

00:00:00.000 --> 00:00:10.000 align:end
Hello

It seems natural to expect that the cue will be right aligned *and* positioned
to the right of the video viewport. What happens right now is that the position
setting is still 50% and the cue grows leftwards, making the cue appear more to
the left compared to an align:middle cue.

To make the default behavior more intuitive (without losing expressiveness with
how the two settings can be used together), I suggest that specifying
align:start and not specifying position should make position default to 0%, and
similarly align:end 100%.
