            Bug ID: 174594
           Summary: Cleanup: Use OptionSet to represent marker types
           Product: WebKit
           Version: WebKit Local Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dbates at webkit.org

Class DocumentMarker::MarkerTypes represents bitmask of marker types and duplicates most of the functionality of OptionSet. Unlike OptionSet, DocumentMarker::MarkerTypes does not support iteration and hence code, such as AlternativeTextController::applyAlternativeTextToRange(), uses Vector<DocumentMarker::MarkerType> to represent a set of marker types. We can use OptionSet to support both uses cases in a space- and time- efficient manner.
