Calculate the meeting point between the offset edges for e1 and e2, putting answer in meetco. e1 and e2 share vertex v and face f (may be NULL) and viewed from the normal side of the bevel vertex, e1 precedes e2 in CCW order. Except: if edges_between is true, there are edges between e1 and e2 in CCW order so they don't share a common face. We want the meeting point to be on an existing face so it should be dropped onto one of the intermediate faces, if possible. Offset edge is on right of both edges, where e1 enters v and e2 leave it. When offsets are equal, the new point is on the edge bisector, with length offset/sin(angle/2), but if the offsets are not equal (allowing for this, as bevel modifier has edge weights that may lead to different offsets) then meeting point can be found be intersecting offset lines. If making the meeting point significantly changes the left or right offset from the user spec, record the change in offset_l (or offset_r); later we can tell that a change has happened because the offset will differ from its original value in offset_l_spec (or offset_r_spec).

This code uses a direct solution to the adjustment problem for chains and certain cycles.

And then minimize the spec-matching constraints using the derivative of the least squares residual in terms of that one degree of freedom. Unfortunately, the results are in some cases worse than the general least squares solution for the combined (with weights) problem, so this code is not used.
