ray() or not. Both clip-path and offset-path uses this function, however clip-path
doesn't support the ray shape, while offset-path does, hence the switch.
(WebCore::CSSPropertyParser::parseSingleValue):

  • rendering/PathOperation.h: Added a new subclass of PathOperation called RayPathOperation

to represent ray().
