Sculpt: Reduce the displacement step in the cloth solver
Previously the base displacement for solving the constraints was always
using 0.5, which may introduce artifacts when multiple constraints of
different types are computed for the same vertex. This introduces a
factor that reduces the base displacement of the solver, reducing the
artifacts.
