public int viewToModel(float x,float y,Shape a,Position.Bias[] bias){
  return m_view.viewToModel(x,y,a,bias);
}

public int viewToModel ( float x , float y , Shape a , Position . Bias [ ] bias ) { return m_view . viewToModel ( x , y , a , bias ) ; }
provides a mapping from the view coordinate space to the logical coordinate space of the model .
