           Summary: Clients for optional features should be passed to Page
                    constructor via structure of pointers
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW

          Priority: P2
         Component: WebCore Misc.

Several of the client arguments to the Page constructor are for optional features, for which most platforms pass 0. The use of a structure of pointers would reduce the number of arguments required. The members of the structure would default to 0, so adding a new optional feature would not require updates to the call sites for platforms not using the feature.

Note that this approach is preferred to a setter for each client, as it avoids the time window where no client is provided.
