<P>
Display a chain of images as a tree. It may be a chain of <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/RenderedImage.html" title="class or interface in java.awt.image"><CODE>RenderedImage</CODE></A> or a chain of
 <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/renderable/RenderableImage.html" title="class or interface in java.awt.image.renderable"><CODE>RenderableImage</CODE></A>. Those images are often the result of some operation (i.e. are actually
 instances of <A HREF="http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/RenderedOp.html" title="class or interface in javax.media.jai"><CODE>RenderedOp</CODE></A> or <A HREF="http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/RenderableOp.html" title="class or interface in javax.media.jai"><CODE>RenderableOp</CODE></A>). The image given to the constructor is
 the root of the tree. The root contains the following children nodes:

 <ul>
   <li>One node for each <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/RenderedImage.html#getSources()" title="class or interface in java.awt.image">source image</A>, if any.</li>
   <li>One node for each <A HREF="http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/OperationNode.html#getParameterBlock()" title="class or interface in javax.media.jai">image parameter</A>, if any.</li>
 </ul>

 Each source image can have its own source and parameters. In an analogy to a file system,
 <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/RenderedImage.html#getSources()" title="class or interface in java.awt.image">source images</A> are like directories and
 <A HREF="http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/OperationNode.html#getParameterBlock()" title="class or interface in javax.media.jai">image parameters</A> are like files.

 When a tree node is selected in the left pane, the content of the right pane is adjusted
 accordingly. If the node is an image, a "preview" tab is show together with an "information"
 tab. Informations include the <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/ColorModel.html" title="class or interface in java.awt.image">color model</A>,
 <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/awt/image/SampleModel.html" title="class or interface in java.awt.image">sample model</A>, data type, etc. If the selected tree node
 is a parameter, then the right pane show the parameter value in <A HREF="../../../../../org/geotools/gui/swing/ParameterEditor.html" title="class in org.geotools.gui.swing">some widget</A> appropriate for the parameter type.
