Mainly it is there because that is where it was put first. The initial
idea was that the model would be internal to the AreaTree and not really
need to be known outside.
The development has shown that the case is different and there will be
external implementations, such as caching, which could be created in
other places.

So it would probably be better moved out, so go ahead. The
implementations should also be moved out.

By the way, I have checked that the area tree, renderer and pdf lib are
not holding onto any memory apart from current working objects (when
caching), such as a page and current pdf stream.
