/**

 * <p>

 * <b>Class View</b>. This class represents the gvSIG specific internal window

 * where the maps are displayed and where the events coming from the user are

 * captured.

 * </p>

 * <p>

 * It is composed by three main visual areas:

 * </p>

 * <ol>

 * <li>

 * <b>Map control</b>: the map area located in the right area of the window. It

 * takes up the biggest part of the window.</li>

 * <li>

 * <b>Table of contents (TOC)</b>: is a list of layers displayed in the view.

 * The TOC is located on the left-top corner of the View and is the place where

 * the user can modify the order, the legends, the visibility and other

 * properties of the layers.</li>

 * <li>

 * <b>Map overview</b>: is a small MapControl located in the left-bottom corner

 * of the View where the user can put some layers which summarizes the view. It

 * is used to make the navigation easier and faster.</li>

 * </ol>
