I am confused by the difference between the iso and non-iso cases here.
 Is there any functional difference in the two?  It doesn't look like
the iso case checks for draw_dialogal_roads.

But, despite this difference I guess it is simple enough to find the
right spot to insert the function.

This also indicates this function needs to check for
draw_diagonal_roads.  But since this option only has an effect in
isometric mode...
