 When a polyline curves back on itself, some of its labels sometimes become
 inverted.

 This can be fixed by examining the segments of the polyline that are
 adjacent to the label, and determining in which direction to follow those
 segments in order to maximize the length of the label that is rendered
 right-side-up.

 Previously, all segments in the polyline were examined for each label,
 rather than just the ones adjacent to the label, leading to possible
 problems.
