2pt conical stage for focal-point-outside case
A couple of annoyances here:
1) the prev vector_scale stage is not usable for masking, as NaN values can propagate through
=> switch to actual masking
2) for the outside case, we must select the min root when the gradient is flipped
=> split into two templated stages (_min, _max)
(I'm not convinced that we need to flip the gradient for RP at all; we can investigate later)
