ProcessWorklist()

ResultCode ProcessWorklist	(	const char *	worklistPath,
		const std::function< ResultCode(SkSpan< std::string > args)> &	processCommandFn
	)

Processes multiple inputs in a single invocation by reading a worklist file. The processCommand is invoked with a set of arguments, read from the worklist. A blank line is used to separate one group of arguments from the next group.
