public void general_transform_point( General_transform *transform, Real x, Real y, Real z, Real *x_transformed, Real *y_transformed, Real *z_transformed )

- Transforms a three dimensional point by a general transform,
passing back the result in the last three arguments.

public void general_inverse_transform_point( General_transform *transform, Real x, Real y, Real z, Real *x_transformed, Real *y_transformed, Real *z_transformed )

- Transforms a three dimensional point by the inverse of the
general transform, passing back the result in the last three arguments.

public void copy_general_transform( General_transform *transform, General_transform *copy )

- Creates a copy of the general transform, allocating memory
within the structure as required.

public void create_inverse_general_transform( General_transform *transform, General_transform *inverse )

- Creates a new general transform that is the inverse of the given
one.
