 //  the backing-store (pixels). This can be from out-of-memory, or something
 //  more opaque, like GDI or cairo reported a failure.
 //
 //  To allow the caller to handle the failure, every Create... factory takes an
 //  enum as its last parameter. The default value is kCrashOnFailure. If the
 //  caller passes kReturnNullOnFailure, then the caller is responsible to check
 //  the return result.
