[vtkusers] How to set texture coordinates?

Yes, and for unstructured grids as well.

  vtkPolyData* pd;
  vtkFloatArray* tc = vtkFloatArray::New();
  tc->SetNumberOfComponents( 2 );
  // ... fill in texture coordinates for each vertex ...
  pd->GetPointData()->SetTCoords( tc );
  tc->FastDelete();
