/** The main task of a Plotter is to create graphic objects which have a certain
    logic place within a coordinate system. For example the bars of a bar chart
    are such graphic objects. The created graphic objects need to be of type
    com::sun::star::drawing::Shape.

    <p>
    Within the chart application we differentiate between two 'types' of shapes
    which can be created by a Plotter.
    The first type are shapes which are completely defined by coordinates
    in the logic coordinate system and will be positioned within this logic
    coordinate system. Those shapes are called 'logic shapes'
    or 'logically placed shapes'. For example a rectangle of a bar chart
    is a 'logic shape'.
    </p>

    <p>
    The second type of shapes are those who can not or should not
    be placed in the logic coordinate system. For example consider a three
    dimensional bar chart with text labels for each data point. You probably
    would not like to place the text shapes as three dimensional objects within
    the logic coordinate system, rather you would like to position the texts as
    two dimensional objects on the two dimensional final page. Those shapes are
    called 'illogic shapes' in contrast to 'logic shapes'.
    'Illogic shapes' are always two dimensional and placed on the documents page.
    </p>

    <p>
    For each type of shapes the Plotter gets one Target where it can add
    or remove shapes.
    </p>

    <p> A Plotter is not allowed to set the property 'Transformation' on a
    shape as this will be done elsewhere.
    </p>
