[webvtt] Pull Request: Fix #232: Make "text alignment" definitions match the rendering

zcorpan has just submitted a new pull request for 
https://github.com/w3c/webvtt:

== Fix #232: Make "text alignment" definitions match the rendering ==
The rendering rules apply unicode-bidi:plaintext which isolates
each line. Make the definitions for "text alignment" start/end
match the rendering rules. Drop the "paragraph direction" concept
since it was not used for anything that changes the rendered result.

See https://github.com/w3c/webvtt/pull/237
