 // An Image wraps an image any flavor, be it platform-native GdkBitmap/NSImage,
 // or a SkBitmap. This also provides easy conversion to other image types
 // through operator overloading. It will cache the converted representations
 // internally to prevent double-conversion.
 //
 // The lifetime of both the initial representation and any converted ones are
 // tied to the lifetime of the Image's internal storage. To allow Images to be
 // cheaply passed around by value, the actual image data is stored in a ref-
 // counted member. When all Images referencing this storage are deleted, the
 // actual representations are deleted, too.
 //
 // Images can be empty, in which case they have no backing representation.
 // Attempting to use an empty Image will result in a crash.
