Commit 370631f01f rescaled the quaternion
manifold's group action so the tangent vector norm matches the full
rotation angle, addressing issue #941. While both conventions are
mathematically valid, issue #311 already concluded that the half-angle
one should be kept because too much code depends on it. The rescaling
effectively broke that expectation for existing callers.
Restore the pre-370631f01f71db36b580e5a65790b2a8d9559821 scaling, keep
the rest of that commit's cleanup, and update the documentation and
tests to match.
Fixes #1190

Ceres Solver
Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.
- Non-linear Least Squares problems with bounds constraints.
- General unconstrained optimization problems.
Please see ceres-solver.org for more information.
