    /// keep up with new events. An unresponsive client may be categorized as
    /// "App Not Responding" and targeted for channel closure.

    /// receiving a |TouchResponse| for each |TouchEvent|.|TouchPointerSample|;
    /// non-sample events should return an empty |TouchResponse| table to the
    /// server. Responses for *previous* events are fed to the server on the
    /// *next* call of |Watch| [1]. Each element in the |responses| vector is
    /// interpreted as the pairwise response to the event in the previous
    /// |events| vector; the vector lengths must match. Note that the client's
