Test case "heal surface_to_bspline F2" produces the face shown in the picture " heal surface_to_bspline F2 (pcurve of Invalid face).PNG" on the current MASTER. I.e. some edge is adjusted incorrectly.

Test heal fix_shape A1

     Draw[]> restore [locate_data_file aaa.rle] a
     Draw[]> explode a f
     Draw[]> don a_1
     Draw[]> v2d
     Draw[]> pcu a_1

See "badface A1.PNG" attached picture. Simple cylindrical face. P-curve of the "top"-edge is geometrically attached to the "bottom" one.

ShapeFix does not translate incorrect p-curve. It increases the tolerance only in order to make the face be closed.

Test heal fix_shape F7

has the same problem.
