    /** 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.
