    I think we got to support different 'RenderingMode' like Raster and GL.
    E.g. fonts have to be accessible in both modes, but they have different
    command sequences.
    We have to check, where this element belongs in our description.
    I guess it's on a quite high level.
    The support of GL is one major reason, why I wanted to provide support for
    'IF'-statements in command sequences. See Parameter converter documentation.
    This may become clearer now. So we can support two or more modes in one
    command sequence. that is definitely not possible in any other device
    description.
