Summary WebCore::LocalDefaultSystemAppearance talks to NSApp

WebCore::LocalDefaultSystemAppearance talks to NSApp to get information about the current system appearance (colors, fonts, etc.). This code path is getting hit while computing styles in the WebContent process. It would be nice if we could either broker these calls to the UIProcess, or perhaps cache these values on the WebProcess side, updating when user settings change.

We do cache the system colors, for each color, when it is not in the cache yet. The cache is cleared when the user appearance settings change. https://trac.webkit.org/browser/webkit/trunk/Source/WebCore/rendering/RenderThemeMac.mm#L453
