Detailed Description

Parabolic arc structure.

Structure represents parabola in standard form: x^2 = 4 * distance * y, moved to stored center point and rotated CCW around this point.

Parametric form of parabola: x = t, y = t^2 / (4 * distance).

Section of parabola (parabolic arc) is given by parameters subinterval.
