LatLng ⇢ LngLat

[jfirebaugh]

Switched to [longitude, latitude] coordinate order, matching GeoJSON. We anticipate that mapbox-gl-js will be widely used with GeoJSON, and in the long term having a coordinate order that is consistent with GeoJSON will lead to less confusion and impedence mismatch than will a [latitude, longitude] order.

The following APIs were renamed:

• LatLng was renamed to LngLat
• LatLngBounds was renamed to LngLatBounds
• Popup#setLatLng was renamed to Popup#setLngLat
• Popup#getLatLng was renamed to Popup#getLngLat
• The latLng property of Map events was renamed lngLat

The following APIs now expect array coordinates in [longitude, latitude] order:

• LngLat.convert
• LngLatBounds.convert
• Popup#setLngLat
• The center and maxBounds options of the Map constructor
• The arguments to Map#setCenter, Map#fitBounds, Map#panTo, and Map#project
• The center option of Map#jumpTo, Map#easeTo, and Map#flyTo
• The around option of Map#zoomTo, Map#rotateTo, and Map#easeTo
• The coordinates properties of video and image sources
