           Summary: Refactor EditingStyle::textDirection to return an
                    Optional<WritingDirection> instead of a bool
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

bool textDirection(WritingDirection&) is a little clunky.

A more modern idiom for these kinds of methods is to return an Optional<T> instead, where nullopt corresponds to a false return value.
