/**
 An `MGLBackgroundStyleLayer` is a style layer that covers the entire map. Use a
 background style layer to configure a color or pattern to show below all other
 map content. If the style’s other layers use the Mapbox Streets source, the
 background style layer is responsible for drawing land, whereas the oceans and
 other bodies of water are drawn by `MGLFillStyleLayer` objects.
 
 A background style layer is typically the bottommost layer in a style, because
 it covers the entire map and can occlude any layers below it. You can therefore
 access it by getting the last item in the `MGLStyle.layers` array.
 
 If the background style layer is transparent or omitted from the style, any
 portion of the map view that does not show another style layer is transparent.
