The following functions have been identified as missing from
QD3D, and potential candidates for including in Quesa:

TQ3RationalPoint3D *
Q3Param2D_To3D(
const TQ3Param2D *param2D,
TQ3RationalPoint3D *result);

TQ3Param2D *
Q3RationalPoint3D_ToParam2D(
const TQ3RationalPoint3D *rationalPoint3D,
TQ3Param2D *result);

TQ3RationalPoint3D *
Q3RationalPoint3D_RRatio(
const TQ3RationalPoint3D *p1,
const TQ3RationalPoint3D *p2,
float r1,
