This function modifies the given 'bsurf' by clamping its knotset to
have bezier end conditions.


Specific Errors:

    PK_ERROR_cant_make_bspline   clamping on the bsurf failed and
                                 the bsurf remains unmodified (MILD)


If the bsurf already has bezier end conditions, the function will succeed and
the bsurf will be returned unchanged.
