----------------------------------------------------------------
To get rid of the error it's suficient to process "auto-start-reverse" as a
{{Double.NaN}} (like "auto") in {{SVGMarkerElementBridge}}.
To add the auto-start-reverse support, it is possible to add a flag in
{{Marker}} which, when set, indicates that current coordinates and next
coordinates must be inverted in {{MarkerShapePainter.buildStartMarkerProxy()}}.
Both start and end marker arrowheads will be displayed correctly.
I attached a working patch.
