Returns the angle of the line in degrees.
- Positive values for the angles mean counter-clockwise while negative values
- mean the clockwise direction. Zero degrees is at the 3 o'clock position.
+ The return value will be in the range of values from 0.0 up to but not
+ including 360.0. The angles are measured counter-clockwise from a point
+ on the x-axis to the right of the origin (x > 0).
