Leaflet.GridLayer: Websocket & Cache #210
Description
Websockets
Load tiles async over websockets, instead of img.src. Implement GridLayer.createTile().
Cache
Not necessary to createTile() for each new tile-request, as we can re-use the tiles. (Not sure why Leaflet does this anyway, actually, as they don't really need to either. Perhaps performance gain is minimal.)
