<h3>Log Message</h3>
<pre>Media controls are missing the white backdrop in UIWebViews
https://bugs.webkit.org/show_bug.cgi?id=146251
&lt;rdar://problem/20181345&gt;

Reviewed by Simon Fraser.

Implement two new CALayer subclasses that explicitly set
something that resembles the system appearance for
media-controls-dark-bar-background and media-controls-light-bar-background.
This way, WebKit1 clients get a visible result.

Creating the actual system recipes is tracked by:
https://bugs.webkit.org/show_bug.cgi?id=146250

* WebCore.xcodeproj/project.pbxproj: Add new files.
* platform/graphics/ca/cocoa/PlatformCALayerCocoa.mm:
(PlatformCALayerCocoa::PlatformCALayerCocoa): Use the new CALayer subclasses for
the appropriate layer types.
* platform/graphics/ca/cocoa/WebSystemBackdropLayer.h: Added.
* platform/graphics/ca/cocoa/WebSystemBackdropLayer.mm: Added.
(-[WebLightSystemBackdropLayer init]):
(-[WebLightSystemBackdropLayer setBackgroundColor:]): Only set to a light grey.
(-[WebDarkSystemBackdropLayer init]):
(-[WebDarkSystemBackdropLayer setBackgroundColor:]): Only set to a dark grey.</pre>
