This alternative can be implemented if the layer knows the map projection. The vector layer would be responsible for calling `source.protocol.read({success: callback})` where the callback would call `source.parser.parseFeatures(data, {projection: projection})` (`data` is supplied to the callback and `projection` comes from the map's view).

The layer would maintain a cache of features in the map view's projection, and these would be provided on demand to layer's the renderer.
