So how would you modify the code example I gave, which was:

   public void GridPlotter( StandardQuantity stdQ ){
      Mapping map = stdQ.getCurrentCoordsQuantity().getMapping();

      <then proceed to use the Mapping to transform arbitrary positions
      backwards and forwards between pixel coords and current WCS coords>

   }
