I was playing with the new bezier functions and noticed a small bug in the documentation:

####
bezierQuadratic(`t`

, `p0`

, `p1`

, `p2`

)

Return a quadratic bezier curve at `t`

given the start point `p0`

, control point `p1`

and end point `p2`

.

`(bezierQuadratic should take 5 parameters, ending with p3)`

####
bezierCubic(`t`

, `p0`

, `p1`

, `p2`

)

Return a cubic bezier curve at `t`

given the start point `p0`

, control points `p1`

, `p2`

, and end point `p3`

.

`(bezierQuadratic should take 4 parameters, ending with p2)`

Otherwise, all good. Fast and fun! Will be super helpful for animators, and anybody else who needs to build smooth, precise curves.
