    /** Retrieves a temporary XControl instance for a given output device

        The method GetUnoControl, used to retrieve the XControl whose parent is a given device, only works
        if the SdrUnoObj has already been painted at least once onto this device. However, there are valid
        scenarios where you need certain information on how a control is painted onto a window, without
        actually painting it. For example, you might be interested in the DeviceInfo of a UNO control.

        For those cases, you can contain an XControl which behaves as the control which *would* be used to
        paint onto a window.

        @param  _rWindow
            the window for which should act as parent for the temporary control
        @param  _inout_ControlContainer
            the control container belonging to the window, necessary as context
            for the newly created control. A control container is usually created by calling
            VCLUnoHelper::CreateControlContainer.
            If _inout_ControlContainer is <NULL/>, it will be created internally, and passed to the caller.
            In this case, the caller also takes ownership of the control container, and is responsible for
            disposing it when not needed anymore.
        @return
            The requested control. This control is temporary only, and the caller is responsible for it.
            In particular, the caller is required to dispose it when it's not needed anymore.
