/**
* GraphicsUtilities contains a set of tools to perform
* common graphics operations easily. These operations are divided into
* several themes, listed below.
* Compatible Images
* Compatible images can, and should, be used to increase drawing
* performance. This class provides a number of methods to load compatible
* images directly from files or to convert existing images to compatibles
* images.
* Creating Thumbnails
* This class provides a number of methods to easily scale down images.
* Some of these methods offer a trade-off between speed and result quality and
* shouuld be used all the time. They also offer the advantage of producing
* compatible images, thus automatically resulting into better runtime
* performance.
* All these methodes are both faster than
* {@link java.awt.Image#getScaledInstance(int, int, int)} and produce
* better-looking results than the various drawImage() methods
* in {@link java.awt.Graphics}, which can be used for image scaling.
* Image Manipulation
* This class provides two methods to get and set pixels in a buffered image.
* These methods try to avoid unmanaging the image in order to keep good
* performance.
