just some researchy stuff... nothing really finished, so it's not in  
a state to be defended ;-)
I know that most people's reaction to the stuff will be "just parse  
the source". But that's ok,
I think I will be able to make my point as soon as it's finished.

I need an AST-like representation, possibly compressed later, for the  
whole image.
Currently the image is 204MB large, our of which way over 100MB are  
tokens, which are not
needed... some information of these is needed, but not the tokens  
themselves.
