/**
* <p>A shadow factory generates a drop shadow for any given picture, respecting
* the transparency channel if present. The resulting picture contains the
* shadow only and to create a drop shadow effect you will need to stack the
* original picture and the shadow generated by the factory. If you are using
* Swing you can get this done very easily with the layout
* {@link org.jdesktop.swingx.StackLayout}.</p>
* <h2>Shadow Properties</h2>
* <p>A shadow is defined by three properties:
* <ul>
* <li><i>size</i>: The size, in pixels, of the shadow. This property also
* defines the fuzzyness.</li>
* <li><i>opacity</i>: The opacity, between 0.0 and 1.0, of the shadow.</li>
* <li><i>color</i>: The color of the shadow. Shadows are not meant to be
* black only.</li>
* </ul>
* You can set these properties using the provided mutaters or the appropriate
* constructor. Here are two ways of creating a green shadow of size 10 and
* with an opacity of 50%:
* <pre>
* ShadowFactory factory = new ShadowFactory(10, 0.5f, Color.GREEN);
* // ..
* factory = new ShadowFactory();
* factory.setSize(10);
* factory.setOpacity(0.5f);
* factory.setColor(Color.GREEN);
* </pre>
* The default constructor provides the following default values:
* <ul>
* <li><i>size</i>: 5 pixels</li>
* <li><i>opacity</i>: 50%</li>
* <li><i>color</i>: Black</li>
* </ul></p>
* <h2>Shadow Quality</h2>
* <p>The factory provides two shadow generation algorithms: <i>fast quality blur</i>
* and <i>high quality blur</i>. You can select your preferred algorithm by
* setting the appropriate rendering hint:
* <pre>
* ShadowFactory factory = new ShadowFactory();
* factory.setRenderingHint(ShadowFactory.KEY_BLUR_QUALITY,
* ShadowFactory.VALUE_BLUR_QUALITY_HIGH);
* </pre>
* The default rendering algorihtm is <code>VALUE_BLUR_QUALITY_FAST</code>.</p>
* <p>The current implementation should provide the same quality with both
* algorithms but performances are guaranteed to be better (about 30 times
* faster) with the <i>fast quality blur</i>.</p>
* <h2>Generating a Shadow</h2>
* <p>A shadow is generated as a <code>BufferedImage</code> from another
* <code>BufferedImage</code>. Once the factory is set up, you must call
* {@link #createShadow} to actually generate the shadow:
* <pre>
* ShadowFactory factory = new ShadowFactory();
* // factory setup
* BufferedImage shadow = factory.createShadow(bufferedImage);
* </pre>
* The resulting image is of type <code>BufferedImage.TYPE_INT_ARGB</code>.
* Both dimensions of this image are larger than original image's:
* <ul>
* <li>new width = original width + 2 * shadow size</li>
* <li>new height = original height + 2 * shadow size</li>
* </ul>
* This must be taken into account when you need to create a drop shadow effect.</p>
* <h2>Properties Changes</h2>
* <p>This factory allows to register property change listeners with
* {@link #addPropertyChangeListener}. Listening to properties changes is very
* useful when you emebed the factory in a graphical component and give the API
* user the ability to access the factory. By listening to properties changes,
* you can easily repaint the component when needed.</p>
* <h2>Threading Issues</h2>
* <p><code>ShadowFactory</code> is not guaranteed to be thread-safe.</p>
