The parametric eqn for a cubic Bezier is, from PLRM:

r(t) = at^3 + bt^2 + ct + r0

with the control points:

r1 = r0 + c/3
|
|
r2 = r1 + (c + b)/3
|

r3 = r0 + c + b + a
|

A quadratic Bezier has the form:
|
|
p(t) = (1-t)^2 p0 + 2(1-t)t p1 + t^2 p2

So equating powers of t leads to:

r1 = 2/3 p1 + 1/3 p0

r2 = 2/3 p1 + 1/3 p2
