I am not sure why that would make the code not object orientated. Inheritance 
is a central feature of object orientated programming. And we dynamic_cast all 
over the place anyway.

There is no strange stuff involved. For now it is easier for me to keep it 
outside KoShape. However once the code is in a more ready state, the functions 
from SvgSerializable can be put into KoShape easily.
