StringPicture class
Decodes the given String as a picture, associating it with the given scale.
The provided String should not be changed after it is provided to a StringPicture. To provide an PictureStream that represents a picture that changes over time, consider creating a new subclass of PictureProvider whose load method returns a subclass of PictureStreamCompleter that can handle providing multiple pictures.
