comment Cubic Bezier Curves - Calculate Y for any given X
Sorry, I misunderstood your question then. The function xAtY first converts a quadratic bezier to power basis form. The resulting quadratic equation is solved to find the t corresponding to the given Y. The bezier curve is then evaluated at the two roots to get the X.
