One thing I have not figured out is the function of the "UseOrientation" argument shown in TYPViewer for the Polylines.
Maybe the answer can be found by reading help files or manuals but that is not the way we seek information...
AFAIK, this applies only to the pattern of a polyline, not the label.
See the tooltip for the "Use orientation": [Only registered and activated users can see links. ]
See also the mkgmap TYP file compiler documentation:
