Architectural changes:
</FONT>
</H1>
<UL>
<LI>
Separation of model, view and controller
<UL>
<LI>
The separation of the different duties will help to maintain and expand the code easier in future.
</LI>
</UL>
</LI>
<LI>
Separation of chart and drawing layer (first part)
<br>
Chart2 uses UNO API to create the draw shapes whereever possible
instead of inheriting from native drawing layer classes.
<UL>
<LI>
This will ease architectural changes in the drawing layer in future.
</LI>
</UL>
</LI>
<LI>
Chart2 is not sfx-based anymore but uses the framework via UNO API instead
<UL>
<LI>
This separation will help with the ongoning effort to replace sfx.
