fix for bug report

According to the spec the GLU_NURBS_VERTEX and GLU_NURBS_VERTEX_DATA callbacks should always return affine coordinates. But in case of a NURBS curve definition in homogeneous coordinates it returns homogeneous coordinates. The transformation to affine coordinates is missing. See accompanying patch for a fix.
