/** The main task of a Plotter is to create grafic objects which have a certain
logic place within a coordinate system. For example the bars of a barchart
are such grafic objects. The created grafic objects need to be of type
com::sun::star::drawing::Shape.
<p>
Within the chart application we differentiatebetween 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.

The type of this implicit used source coordinate system has to be
returned here.
