At row 3214 changed  

public float bezierPoint(float a, float b, float c, float d, float t) {
  float t1 = 1.0f - t;
  return a*t1*t1*t1 + 3*b*t*t1*t1 + 3*c*t*t*t1 + d*t*t*t;
}

to  

float bezierPoint (float a, float b, float c, float d, float t) {
  float t1 = t-1.0f;
  return t * ( 3*t1*(b*t1-c*t) + d*t*t ) - a*t1*t1*t1;
}
, works the same but faster
