Two-dimensional arcs, approximated by cubic bezier curves.

arc :: Angle -> Angle -> Path R2Source
Given a start angle s
and an end angle e
(both in radians),
is the path of a radius one arc counterclockwise
between the two angles.

bezierFromSweep :: Angle -> [Segment R2]Source
bezierFromSweep s
constructs a series of Cubic
segments that
start in the positive y direction and sweep counter clockwise
through s
radians. If s
is negative, it will start in the
negative y direction and sweep clockwise. When s
is less than
0.0001 the empty list results. If the sweep is greater than two pi
then it is truncated to two pi.
