Hi Thomas,

I am starting to slowly see some of the potential issues related to 
trying to have full support for all rendering features (alignment of 
dash lines between the AGG hi-res and the UTFGrid low-res versions comes 
to mind for instance).

Anyway, I'm starting to settle on the idea of a simpler implementation. 
And as you write there is still a good amount of work left to be done 
apart from the rendering itself. We'll be discussin this in the code 
review with François tomorrow. If you'd like to join let us know and we 
can arrange something.
