Rotate the object to have the same angle as the segment it is at; use this orientation for arrow heads.
Rotate the object counter-clockwise 90 degrees to be perpendicular to the angle of the segment it is at.
Do not rotate the object along the segment.
Rotate the object to be 180 degrees opposite from the angle of the segment it is at.
Rotate the object clockwise 90 degrees to be perpendicular to the angle of the segment it is at.
Rotate the object to have the same angle as the segment it is at, but never upside down and never angled more than +/- 45 degrees: when the segment's angle is with 45 degrees of vertical (90 or 270 degrees), the object's angle is set to zero; this is typically only used for TextBlocks or Panels that contain text.
This enumeration specifies possible values for GraphObject.segmentOrientation.
