Function flo_curves::bezier::nearest_point_on_curve

pub fn nearest_point_on_curve<C>(curve: &C, point: &C::Point) -> f64where
    C: BezierCurve + BezierCurve2D,
    C::Point: Coordinate + Coordinate2D,

Finds the ‘t’ value of the closest point on a curve to the supplied point

Note that in interactive applications the true ‘closest’ point may not be the most useful for the user trying to indicate a point on the curve. This is because on the inside of convex regions of the curve, a moving point far enough away will jump between the end points of the convex region. Consider using ray-casting instead via curve_intersects_ray() instead to find points that the user might be indicating instead.
