Theodore Abshire d46e8fdf92 Typo fixes and rewording in comments, part 6
This makes a large number of small typo fixes. It also rewords a
number of comments and JSDoc descriptions, and does some
formatting standardization.

This doesn't fix every single issue, but it fixes a lot. Notably,
there were some formatting issues I declined to standardize due to
ambivalence on what the proper standardization would be; for example,
when and where empty lines should show up in JSDoc.

Jacob Trimble 624acc66b8 Add curly braces to all blocks.
Google style guide requires adding curly braces to all block statements
even if it is only has one line.  This fixes it by using eslint's
--fix flag followed by running clang-format to reformat the change.

Jacob Trimble b512db87dd Convert 'var' to 'let'/'const' (8 of 9).
This is part of a change to convert all usages of 'var' with either
'let' or 'const'.  This takes a conservative approach for 'const' where
it will only be used for aliases and storing the "original" values in
tests.

Joey Parrish 14d91b0be8 Improve annotations and docs for TtmlTextParser
During docs review, I noticed that shaka.text.TtmlTextParser's
textAlignToLineAlign_ was defined as merely {Object}.  Improving that
to {Object.<string, string>} caused compiler issues, so I had to
further refine to {Object.<string, shaka.text.Cue.lineAlign>} and
refer to the enum values instead of directly using strings.

Joey Parrish 66bfa31538 Do not use VTTRegion yet
Our use of VTTRegion seems to be wrong.  The feature in Chrome is
behind the "experimental web platform features" flag.  If this is
turned on, we display subtitles in the wrong place.

Until we can verify and fix our usage of VTTRegion, we will not
use it.  There are other issues to deal with in our region support,
in particular that TTML uses px and VTT uses percentages.  Futher,
our VTT parser does not yet extract region information.

This fixes the main issue for v2.3, so that future releases of Chrome
do not break sites built with v2.3.  There is more work to do in v2.4.

Jacob Trimble d997065a02 Fix TTML region parsing.
The tts:origin and tts:extent attributes specify the sub-region to
render cues onto.  We parsed them as positioning info for the cues
themselves.  This converts to using VTTRegion for this.  However, this
is ignored on browsers since none expose VTTRegion as of now.

Closes #1020

Sandra Lokshina c6c6d05810 Move text-related files into their own directory.
This change creates a lib/text directory and moves all files
with text-related logic to it. It also lays the ground for
separating text parsing and display logic. (That change will
introduce even more files with text-related logic which will
crowd lib/media directory).

Issue #796.
