Affected examples

Koch
Fix implementation

Define rotatePVector() (copied from PVector.java)

void rotatePVector(PVector vec, float theta) {
  float xTemp = vec.x;
  vec.x = vec.x*cos(theta) - vec.y*sin(theta);
  vec.y = xTemp*sin(theta) + vec.y*cos(theta);
}

and change v.rotate(...) to rotatePVector(v, ...).
