Example

Remarks

see (tingr:get-midOrdinateDist);

the mid-ordinate distance is the distance of the curve's midpoint, to the arc center; similar to arc's bulge; used as a kind of tolerance;
this curve rasterisation/smoothing tolerance only applies to curve-based constraints;
default value is 0.0, which means automatic tolerance chosen by the TinGrading implementation;
