Changeset 1296 in josm for trunk/src

Timestamp:

Message:

add mappaint.lefthandtraffic option to distinguish if the turn restriction signs must be placed to the right (default) or to the left of the street (setting might be useful elsewhere ...)

fix a bug when the heading of the "from" way was exactly 0/180 degrees
