Summary0002172: [Solver] Showcase LevenbergMaquardt succeded where DogLeg failed
DescriptionThis sketch consistently fails to be solved with DL and is consistently solved with LM.

As point dragging is done with DL (I will have to make this configurable in the future and do dragging failback at least with LM), all point dragging fails, but I can continue working because every constraint will be solved by LM.

Steps To ReproduceFirst:

1. Load the Sketch.
2. Create a line
3. Try to drag the endpoints of the line, see report window

Second:

1. Try for example to continue doing a symmetrical sketch of the one in the left, in the right part.
2. Look at the report window, LM solves the sketch DL fails.

There is a line at the origin that has both endpoints coincident with the origin. This is the source of all evil.
