code: public RendererJob otherTile(Tile tile) {
          return new RendererJob(tile, this.mapDataStore, this.renderThemeFuture, this.displayModel, this.textScale, this.hasAlpha, this.labelsOnly);
      }
docs: Just a way of generating a hash key for a tile if only the RendererJob is known.
  
  @param tile the tile that changes
  @return a RendererJob based on the current one, only tile changes
