* claim: #4585

* Sketch drag: a linkage held by redundant parallelograms still moves (#4585)

Cursor motion looks for the sketch's freedom in the null space of the
constraint Jacobian. Redundant constraints (a parallelogram held both
parallel and equal on each pair of sides) are dependent only at an exact
solution; after a correction to the solver's tolerance their rows differ
by about 1e-9, which the 1e-9 pivot tolerance counted as rank, so the
null space came out empty and a one-DoF linkage stayed locked. Use the
rank analysis' 1e-7, so the drag sees the freedom the sketch reports.
