arcCRAA
Makes an arc given a center, radius and two angles. An arc is a portion of a circle.
The angles are measured
from the positive x-axis of the drawing plane. This is usually the least convenient
way to make an arc, but in cases where you know the center and radius it is a
nice function to have.
center :
Point
Center of arc.
radius :
Scalar
Radius of arc
angleA :
Angle
Angle from x-axis of arc start
angleB :
Angle
Angle from x-axis of arc end
