The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

/**
|
|
* Overview of WebVTT cuetext and anonymous content setup.
|
|
*
|
|
* WebVTT nodes are the parsed version of WebVTT cuetext. WebVTT cuetext is
|
|
* the portion of a WebVTT cue that specifies what the caption will actually
|
|
* show up as on screen.
|
|
*
|
|
* WebVTT cuetext can contain markup that loosely relates to HTML markup. It
|
|
* can contain tags like <b>, <u>, <i>, <c>, <v>, <ruby>, <rt>, <lang>,
|
|
* including timestamp tags.
|
|
*
|
|
* When the caption is ready to be displayed the WebVTT nodes are converted
|
|
* over to anonymous DOM content. <i>, <u>, <b>, <ruby>, and <rt> all become
|
|
* HTMLElements of their corresponding HTML markup tags. <c> and <v> are
|
|
* converted to <span> tags. Timestamp tags are converted to XML processing
|
|
* instructions. Additionally, all cuetext tags support specifying of classes.
|
|
* This takes the form of <foo.class.subclass>. These classes are then parsed
|
|
* and set as the anonymous content's class attribute.
|
|
*
|
|
* Rules on constructing DOM objects from WebVTT nodes can be found here
|
|
* http://dev.w3.org/html5/webvtt/#webvtt-cue-text-dom-construction-rules.
|
|
* Current rules are taken from revision on April 15, 2013.
