2016876 - Add ViewTimeline interface and its readonly attributes

Status: RESOLVED FIXED

(Core :: DOM: Animation, enhancement)

Description

[Boris Chiou [:boris]]

The interface looks like:

[Exposed=Window]
interface ViewTimeline : ScrollTimeline {
  ...
  readonly attribute Element subject;
  readonly attribute CSSNumericValue startOffset;
  readonly attribute CSSNumericValue endOffset;
};

However, CSSNumericValue depend on CSS Typed OM, so for now we could just use double to present the percentage.
We will do the constructor in another bug.
