<pre>[iOS] Play glyph is pixelated when the page zoom is large
https://bugs.webkit.org/show_bug.cgi?id=158770
<rdar://problem/26092124>
Patch by Antoine Quint <graouts@apple.com> on 2016-06-14
Reviewed by Dean Jackson.
Use the same technique that we use to scale the video controls by using a combination
of CSS "zoom" and "transform" properties to have the video play glyph scaled at its
native size regardless of page zoom.
* Modules/mediacontrols/mediaControlsiOS.js:
(ControllerIOS.prototype.set pageScaleFactor):</pre>
