Summary0003110: Sketcher: add support of relevant constraints to B-splines
DescriptionThe current implementation of B-splines only support constraints on the B-spline vertices. It would be useful to use other constraints as well (point on object, tangent, perpendicular on the curve).

Can this be broken down into two parts?

(1) BSpline is immutable and the other simpler geometry is forced to conform to it -- eg lines are forced equal length or forced perpendicular at point of intersection while the BSpline remains constant.

(2) BSpline can be fully effected and changed by the constraints.

I am looking to use the Length Equality between line and BSpline, which should be the easiest thing, it has to measure it and then apply it.
