This options structure defines optional controls for lowering the degree of
a bsurface.

Used in:

PK_BSURF_lower_degree

 'have_tolerance'   Whether a tolerance has been provided.  If this
                    is PK_LOGICAL_true, then the bsurf will not be
                    changed by more than 'tolerance'.  If this is
                    PK_LOGICAL_false, exact degree reduction will be
                    attempted, and 'tolerance' will be ignored.

 'tolerance'        The tolerance for the degree reduction.
