WebView component's emitEvent bottleneck

General JUCE discussion

I think I have identified a bottleneck in juce_WebBrowserComponent.cpp/emitEvent.
When you send over large objects: When replacing escapes:


    void emitEvent (const Identifier& eventId, const var& object)
    {
        ...
        const auto objectAsString = JSON::toString (object, true); //THIS IS SUPER SLOW FOR LAAAARGE OBJECTS!
        ...
        evaluateJavascript ("window.__JUCE__.backend.emitByBackend(" + eventId.toString().quoted() + ", "
                                + escaped.quoted ('\'')
                                + ");", evaluationHandler);
    }

    void emitEvent(const Identifier& eventId, const var& object) {
        const auto objectAsString = JSON::toString (object, true);
        // This eliminates the need for expensive string replacements
        evaluateJavascript ("window.__JUCE__.backend.emitByBackend(" + eventId.toString().quoted() + ", "
                               + "atob(" + Base64::toBase64(objectAsString).quoted() + ")"
                               + ");", evaluationHandler);
    }

Would that make sense to add?
