Functions
DeterminantPolynomial	serif::geometry::deformation::detail::determinant_polynomial (const JacobianEntries &base, const JacobianEntries &direction, int dimension, double maximum_step, double determinant_floor) noexcept
	Expand det(base + t maximum_step direction) minus the floor for dimensions one through three.
double	serif::geometry::deformation::detail::evaluate_polynomial (const DeterminantPolynomial &coefficients, double parameter) noexcept
	Evaluate the cubic with fused operations, retaining small values near repeated roots.
double	serif::geometry::deformation::detail::first_boundary_parameter (const DeterminantPolynomial &coefficients) noexcept
	Find the first loss of strict positivity in (0, 1], including a tangent zero.
