2016879 - Add the constructor of ViewTimeline interface

Status: NEW

(Core :: DOM: Animation, enhancement)

Description

[Boris Chiou [:boris]]

Now it's time to add the constructor for ViewTimeline:

dictionary ViewTimelineOptions {
  Element subject;
  ScrollAxis axis = "block";
  (DOMString or sequence<(CSSNumericValue or CSSKeywordValue)>) inset = "auto";
};

[Exposed=Window]
interface ViewTimeline : ScrollTimeline {
  constructor(optional ViewTimelineOptions options = {});
  ...
};

We have to add ViewTimelineOptions as well. However, before we enable CSS Typed OM, we can restrict the inset to be (<DOMString or sequence<(double or DOMString)>). The double here is the length value (and so we don't accept percentage for now). This is just a tentative syntax and we will fix it in the following bug.
