The problem data (SmSurfacePointSolver), the global solver's helpers
(closure cache, objective, control-net triangle and leg guesses, seam,
stride, extremum and boundary tests) and the local stepper's pieces
(construction, copies, lazy evaluation, clamping, boundary hits, bounds
check, iso-curve drop) of SmSurfacePointSolve.cpp, with the static
control-net helpers.
The shim compiles the upstream file itself (its classes are file-local),
renaming the classes and SmSurface's two point-solve members.
