/**
* <p><code>GraphicsUtilities</code> contains a set of tools to perform
* common graphics operations easily. These operations are divided into
* several themes, listed below.</p>
* <h2>Compatible Images</h2>
* <p>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.</p>
* <h2>Creating Thumbnails</h2>
* <p>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.</p>
* <p>All these methodes are both faster than
* {@link java.awt.Image#getScaledInstance(int, int, int)} and produce
* better-looking results than the various <code>drawImage()</code> methods
* in {@link java.awt.Graphics}, which can be used for image scaling.</p>
* <h2>Image Manipulation</h2>
* <p>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.</p>
