/**
* Defines two methods to convert between a {@link Frame} and another generic
* data object that can contain the same data. The idea with this design is
* to allow users to convert easily between multiple potentially mutually
* exclusive types of image data objects over which we have no control. Because
* of this, and for performance reasons, any object returned by this class is
* guaranteed to remain valid only until the next call to {@code convert()},
* anywhere in a chain of {@code FrameConverter} objects, and only as long as
* the latter themselves are not garbage collected.
