Description and/or steps/code to reproduce the problem

TileLooper.java has a method : loop(final double pZoomLevel, final RectL pMercatorViewPort);
`

protected void loop(final double pZoomLevel, final RectL pMercatorViewPort)
{

TileSystem.getTileFromMercator(pMercatorViewPort, TileSystem.getTileSize(pZoomLevel), mTiles);

mTileZoomLevel = TileSystem.getInputTileZoomLevel(pZoomLevel);

initialiseLoop();

final int mapTileUpperBound = 1 << mTileZoomLevel;

  /* Draw all the MapTiles (from the upper left to the lower right). */
  for (int i = mTiles.left ; i <= mTiles.right ; i ++) {
      for (int j = mTiles.top ; j <= mTiles.bottom ; j ++) {
	      if ((horizontalWrapEnabled || (i >= 0 && i < mapTileUpperBound)) && (verticalWrapEnabled
			      || (j >= 0 && j < mapTileUpperBound))) {
		      final int tileX = MyMath.mod(i, mapTileUpperBound);
		      final int tileY = MyMath.mod(j, mapTileUpperBound);
		      final long tile = MapTileIndex.getTileIndex(mTileZoomLevel, tileX, tileY);
		      handleTile(tile, i, j);
	      }
      }
  }
  
  finaliseLoop();

}
`
now,"int mapTileUpperBound = 1 << mTileZoomLevel" only support the osm style map, can not load the map tiles when the zoom is 0 ,but it has more than one tiles,such as the arcgis offline files.
