<P>
Abstracts the underlying platform graphics context thus allowing us to achieve portability between MIDP devices and CDC devices. This abstaction simplifies and unifies the Graphics implementations of various platforms. <p>A graphics instance is never created by the developer and is always accessed using either a paint callback or a mutable image. There is no way to create this object directly.
