Support bounds in TileJSON

[steinbachr]

the combination of documentation here which states, "Tiled sources (vector and raster) must specify their details in terms of the TileJSON specification" and the TileJSON documentation here leads me think it's possible to add a raster source that only adds tiles within certain bounds. However, when I try to do so, the entire map is tiled, rather than just the portion of map contained within bounds. For instance, this code tiles the entire map without respect to bounds whereas I would expect it to tile only within the bounds given ([-10, -10, 10, 10]):

"raster-layer": {
      "type": "raster",
      "tiles": [
           "https://some-tile-source/{z}/{x}_{y}.jpg"
       ],
      "bounds": [-10, -10, 10, 10],
      "tileSize": 256,
      "minzoom": 0,
      "maxzoom": 5
}

You're right, TileJSON bounds is something that should be supported, but isn't currently.

ah okay, thanks for the clarification @jfirebaugh

We are using something like this to avoid requests to tiles which are located outside of a given bounding box:
