Style resolution: Apply animation properties earlier in a separate pass

Source/core/css/CSSPropertyNames.in

 //
 // CSS property names
 //
 // Some properties are used internally, but are not part of CSS. They are used to get
 // HTML4 compatibility in the rendering engine.
 //
 // Microsoft extensions are documented here:
 // http://msdn.microsoft.com/workshop/author/css/reference/attributes.asp
 //
 
-// high-priority property names have to be listed first, to simplify the check
-// for applying them first.
+// properties that generate animations must be listed first
