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.</pre>
