fz_nsrf_sample_srf_parameter_based2

Description

Samples NURBS surface along the parameter domain to obtain points. The list ( fz_type_list_ptr) passed in needs to be initialized before calling this function. The sample points are returned in the given list row-wise. That is, a row of v control points for the first u value is returned first. Then, the row of v control points for the next u value. Optionally, the [u,v]s corresponding to the sample points are returned in the uv list, which is parallel to the point list and also needs to be intialised.
