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

Used in:

PK_BCURVE_lower_degree

'have_tolerance'         Whether a tolerance has been provided.  If this
                         is PK_LOGICAL_true, then the bcurve 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.
                         (PK_LOGICAL_false)

'tolerance'              The tolerance for the degree reduction.
