[Freeciv-Dev] (PR#2408) Problem with diagonal roads and rails

["Guest via RT" <rt@xxxxxxxxxxxxxx>]

The proposed patch looks good for overhead, but isn't really needed for
isometric.  REmember thaat isometric tiles aren't simply diamonds, but
container the are above them:
+---+
|   |
|   |
\   /
 \ /
  V
This allows northeast/southwest rails to proceed normally, just slightly
raised up.  Admittedly, there is a small interruption in
northwest/southeast railst, but it is only one pixel for rails 6 pixels
wide, and I think we can ignore that.

It's a good move for overhead, though.
