+/**
+ `MGLImageSource` is a content source that is used for a georeferenced raster
+ image to be shown on the map. The georeferenced image scales and rotates as the
+ user zooms and rotates the map. Images may also be used as icons or patterns 
+ in a style layer. To register an image for use as an icon or pattern, 
+ use the `-[MGLStyle setImage:forName:]` method. To configure a point 
+ annotation’s image, use the `MGLAnnotationImage` class.
+ 
+ The geographic location of the raster image content, supplied with 
+ `MGLCoordinateQuad`, can be non-axis aligned.
+ `MGLImageSource` supports raster content from `NSURL`, `NSImage` (macOS), or 
+ `UIImage` (iOS).
+ An image source is added to an `MGLStyle` object along with one or more
+ `MGLRasterStyleLayer` objects. Use a raster style layer to control the
+ appearance of content supplied by the image source.
+ 
+ Each
+ <a href="https://www.mapbox.com/mapbox-gl-style-spec/#sources-image"><code>image</code></a>
+ source defined by the style JSON file is represented at runtime by an
+ `MGLImageSource` object that you can use to initialize new style layers. You
+ can also add and remove sources dynamically using methods such as
+ `-[MGLStyle addSource:]` and `-[MGLStyle sourceWithIdentifier:]`.
+
+ ### Example
+
+ ```swift
+ let coordinates = MGLCoordinateQuad(
+   topLeft: CLLocationCoordinate2D(latitude: 46.437, longitude: -80.425),
+   bottomLeft: CLLocationCoordinate2D(latitude: 37.936, longitude: -80.425),
+   bottomRight: CLLocationCoordinate2D(latitude: 37.936, longitude: -71.516),
+   topRight: CLLocationCoordinate2D(latitude: 46.437, longitude: -71.516))
+ let source = MGLImageSource(identifier: "radar", coordinateQuad: coordinates, url: URL(string: "https://www.mapbox.com/mapbox-gl-js/assets/radar.gif")!)
+ mapView.style?.addSource(source)
+ ```
