[mkgmap-dev] [PATCH v1] Remove one direction of motorways in overview

Mon May 13 21:55:58 BST 2013

Attached patch gives a little try how we could remove the duplicate 
motorways in the overview map. Usually both directions of a motorway are 
painted on each other.

The patch removes all motorway segments from the overview map that span 
an angle 0° to 180° between first and last point of a segment.

It should not be commited because I think we could do better with a 
specialized filter (?) but it's an easy prototype to check if it's 
worthy to start such an implementation.
