This structure holds options for PK_CURVE_is_isoparam.

Used in:

PK_CURVE_is_isoparam

This options structure defines options for controlling what extra information
is returned when a curve is tested for being a constant-parameter curve on a
given surface.

If the curve is determined to not be a constant-parameter curve for the given
surface, these options have no effect. Otherwise:

'want_interval'  Whether to compute the range of the surface's non-constant
                 parameter occupied by the curve. (PK_LOGICAL_false)

'want_alignment' Whether to compute if the surface's non-constant parameter
                 is increasing or decreasing with respect to the curve's
                 parameterisation. (PK_LOGICAL_false)
