[vtkusers] get tcoords from pointId

Hi Marco,

Texture coordinates are stored in an array in a vtkDataSet's
vtkPointData object. Say you have a vtkPolyData with texture
coordinates. To access it, you would do something like

vtkPointData* pd = polyData->GetPointData();
vtkDataArray* tcoords = pd->GetTCoords();

// Let's assume the tcoords are in a vtkFloatArray
vtkFloatArray* floatTcoords = vtkFloatArray::SafeDownCast(tcoords);
if (floatTCoords)
  float texCoord[3];
  floatTcoords->GetTupleValue(pointId, texCoord);

  // do something with texCoord

I hope that helps,
