Detailed Description

Hyperbola or hyperbolic arc.

Structure represents hyperbola in standard form: x^2 / major^2 - y^2 / minor^2 = 1, moved to stored center point and rotated CCW around this point.

FIXME: domyslet vhodnou parametrizaci

Parametric form (interval (0, PI) for right branch, (-PI, 0) for left branch): x = a / sin t, y = b * cos t / sin t.

Section of hyperbola (hyperbolic arc) is given by parameters subinterval (cannot contain zero).
