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.
`arc`

s e

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.
