* Possible solution: TextFactory does not return the complete text. It returns
* the text up to the last whitespace encountered and returns the text chunk
* only if either finishText has been called or some more text comes in. The
* ugly sideffect: Text may result in more than one renderable text chunk
* returned.
* <p/>
* If we return lines (broken by an LineBreak-occurence) we can safe us a lot of
* trouble later.
