Function fit_projected_pcurve 

pub fn fit_projected_pcurve(
    curve: &Curve,
    range: (f64, f64),
    surface: &SurfaceGeometry,
    tol: Tolerances,
) -> FittedPcurve

Fit a pcurve by projection at the reader’s own line: slop under a millimetre is a file’s error, honestly carried; anything past it is a wrong pairing and refuses. The exchange readers call this; a healer acting on instruction calls fit_projected_pcurve_capped with the cap its caller chose.

Errors

As fit_projected_pcurve_capped, at the millimetre cap.
