-/**
- * @class Ext.layout.AnchorLayout
- * @extends Ext.layout.ContainerLayout
- * <p>This is a layout that enables anchoring of contained elements relative to the container's dimensions.
- * If the container is resized, all anchored items are automatically rerendered according to their
- * <b><tt>{@link #anchor}</tt></b> rules.</p>
- * <p>This class is intended to be extended or created via the layout:'anchor' {@link Ext.Container#layout}
- * config, and should generally not need to be created directly via the new keyword.</p>
- * <p>AnchorLayout does not have any direct config options (other than inherited ones). By default,
- * AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
- * container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.
- * If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating
- * anchor measurements based on it instead, allowing the container to be sized independently of the anchoring
- * logic if necessary.  For example:</p>
- * <pre><code>
-var viewport = new Ext.Viewport({
-    layout:'anchor',
-    anchorSize: {width:800, height:600},
-    items:[{
-        title:'Item 1',
-        html:'Content 1',
-        width:800,
-        anchor:'right 20%'
-    },{
-        title:'Item 2',
-        html:'Content 2',
-        width:300,
-        anchor:'50% 30%'
-    },{
-        title:'Item 3',
-        html:'Content 3',
-        width:600,
-        anchor:'-100 50%'
-    }]
-});

-     * <p>This value is what tells the layout how an item should be anchored to the container. <tt>items</tt>
-     * added to an AnchorLayout accept an anchoring-specific config property of <b>anchor</b> which is a string
-     * containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%').
-     * The following types of anchor values are supported:<div class="mdetail-params"><ul>
-     * 
-     * <li><b>Percentage</b> : Any value between 1 and 100, expressed as a percentage.<div class="sub-desc">
-     * The first anchor is the percentage width that the item should take up within the container, and the
-     * second is the percentage height.  For example:<pre><code>
-// two values specified
-anchor: '100% 50%' // render item complete width of the container and
-                   // 1/2 height of the container
-// one value specified
-anchor: '100%'     // the width value; the height will default to auto
-     * </code></pre></div></li>
-     * 
-     * <li><b>Offsets</b> : Any positive or negative integer value.<div class="sub-desc">
-     * This is a raw adjustment where the first anchor is the offset from the right edge of the container,
-     * and the second is the offset from the bottom edge. For example:<pre><code>
-// two values specified
-anchor: '-50 -100' // render item the complete width of the container
-                   // minus 50 pixels and
-                   // the complete height minus 100 pixels.
-// one value specified
-anchor: '-50'      // anchor value is assumed to be the right offset value
-                   // bottom offset will default to 0
-     * </code></pre></div></li>
-     * 
-     * <li><b>Sides</b> : Valid values are <tt>'right'</tt> (or <tt>'r'</tt>) and <tt>'bottom'</tt>
-     * (or <tt>'b'</tt>).<div class="sub-desc">
-     * Either the container must have a fixed size or an anchorSize config value defined at render time in
-     * order for these to have any effect.</div></li>
-     *
-     * <li><b>Mixed</b> : <div class="sub-desc">
-     * Anchor values can also be mixed as needed.  For example, to render the width offset from the container
-     * right edge by 50 pixels and 75% of the container's height use:
-     * <pre><code>
