Subject: Change map image interpolation to a more precise one.
X-Git-Url: https://git.street.me.uk/andy/viking.git/commitdiff_plain/2d5d32c172fd71ee4b4230b9b83b7dccfa1e14f1

Change map image interpolation to a more precise one.

Although this is slightly slower - it is not called often,
 not noticeable on modern systems and the result will get added the map memory cache anyway.
