-/**
- * Instances of this class provide the appearance and
- * behavior of <code>Shells</code>, but are not top
- * level shells or dialogs. Class <code>Shell</code>
- * shares a significant amount of code with this class,
- * and is a subclass.
- * <p>
- * IMPORTANT: This class was intended to be abstract and
- * should <em>never</em> be referenced or instantiated.
- * Instead, the class <code>Shell</code> should be used.
- * </p>
- * <p>
- * Instances are always displayed in one of the maximized, 
- * minimized or normal states:
- * <ul>
- * <li>
- * When an instance is marked as <em>maximized</em>, the
- * window manager will typically resize it to fill the
- * entire visible area of the display, and the instance
- * is usually put in a state where it can not be resized 
- * (even if it has style <code>RESIZE</code>) until it is
- * no longer maximized.
- * </li><li>
- * When an instance is in the <em>normal</em> state (neither
- * maximized or minimized), its appearance is controlled by
- * the style constants which were specified when it was created
- * and the restrictions of the window manager (see below).
- * </li><li>
- * When an instance has been marked as <em>minimized</em>,
- * its contents (client area) will usually not be visible,
- * and depending on the window manager, it may be
- * "iconified" (that is, replaced on the desktop by a small
- * simplified representation of itself), relocated to a
- * distinguished area of the screen, or hidden. Combinations
- * of these changes are also possible.
- * </li>
- * </ul>
- * </p>
- * Note: The styles supported by this class must be treated
- * as <em>HINT</em>s, since the window manager for the
- * desktop on which the instance is visible has ultimate
- * control over the appearance and behavior of decorations.
- * For example, some window managers only support resizable
- * windows and will always assume the RESIZE style, even if
- * it is not set.
- * <dl>
- * <dt><b>Styles:</b></dt>
- * <dd>BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL</dd>
- * <dt><b>Events:</b></dt>
- * <dd>(none)</dd>
- * </dl>
- * Class <code>SWT</code> provides two "convenience constants"
- * for the most commonly required style combinations:
- * <dl>
- * <dt><code>SHELL_TRIM</code></dt>
- * <dd>
- * the result of combining the constants which are required
- * to produce a typical application top level shell: (that 
- * is, <code>CLOSE | TITLE | MIN | MAX | RESIZE</code>)
- * </dd>
- * <dt><code>DIALOG_TRIM</code></dt>
- * <dd>
- * the result of combining the constants which are required
- * to produce a typical application dialog shell: (that 
- * is, <code>TITLE | CLOSE | BORDER</code>)
- * </dd>
- * </dl>
- * <p>
- * IMPORTANT: This class is intended to be subclassed <em>only</em>
- * within the SWT implementation.
