~Private()

KisImageResolutionProxy::Private::~Private ( )

Since we are not using QObject for the connection, we should disconnect the connection automatically on destruction.

        if (imageConnection) {
            QObject::disconnect(imageConnection);

NOTE: we cannot just use detached converter all the time, because we cannot update its values in time before the next update after image changed its resolution (the signal is emitted at the very end of the operation).

The layer will keep "the lastly used resolution" until being attached to the new image.
