Ben Harper 05849f0da5 Add new angled-point marker placement mode for lines ...

This adds a new mode called 'angled-point' to the marker-placement modes.
The full list of modes is then:
  point, angled-point, interior, line, vertex-first, vertex-last

Angled point is identical to point, except that when placing a marker on
a line, the marker's angle is taken from the angle of the line segment.

There is another possible use of the "angled-point" concept for polygons,
and that is for placing labels on stand (aka erf) polygons. By computing
a dominant angle for a mostly rectangular polygon, this can produce quite
good results. I'm not sure whether I should implement that now, or if I
could do that later.
