Rendering pixels outside the rectangular tile area (30x30 or 45x45) 
sounds like a change to the rendered module. I've been under the 
impression that the rendered (or the loader) module cannot handle images 
extending beyond the tile edges. Correct me, if I'm wrong.

The information how much border the tiles have must come from somewhere.
It cannot be hardcoded - the required border size depends on the width of
the road. The 'spec' file mentioned in earlier posts would be handy.


Another approach (worth mentioning, but not implementing):

How about using the same technique as for the shores? It requires 
defining 16 corner tiles to fill the nicks. That is 16 for roads and 16 
for railroads. And if the rivers become road-like, for them too. 

This method would probably work with current resources, but introducing 
dozens of new tiles to fix a minor visual ugliness is not worth it.
