doesn anyone no what 
	Node::getCursor(long offset,int &x.int &y, int &height)  
is? 
Does it return the position of a cursor-like line ( | ) with the position of 
the current node and the height of this object/node?

and what is Node::offset good for? i did serveral test with different 
doc-structures but it stayed at value 0.
