PolarCoord class

The specification of a polar coordinate.

In a polar coordinate, dimensions are assigned to angle and radius. The angles are in radians.

The plane of a polar coordinate is defined not only by the coordinate region, but also the starts and ends of angle and radius dimensions on canvas, which are defined by startAngle, endAngle, startRadius, and endRadius.
