[mkgmap-dev] [PATCH v1] Check size of polygons to avoid exceeding subdivision size

Thu Jul 7 17:32:58 BST 2011

Hi Nop,

I am still curious if the patch improves the subdivision creation or 
not. It would be great if you can answer my questions so that I can 
estimate if it makes sense to continue with my first approach.
