case class QCurve(p1: R2, pc: R2, p2: R2, straight: Boolean) extends Double, CurvilinearShape

The QCurve class enhances the QuadCurve.Double class (from the java.awt.geom package) by allowing entities to move along such quadratic curves as well as lines. Although the curve could be developed as a quadratic function where y = ax^2 + bx + c. The following quadratic bezier formulation is used: p(t) = (x(t), y(t)) = [(1-t)^2 * p1] + [2 * (1-t) * t * pc] + [t^2 * p2].
