/**
 * @class Ext.Viewport
 * @extends Ext.Container
 * <p>A specialized container representing the viewable application area (the browser viewport).</p>
 * <p>The Viewport renders itself to the document body, and automatically sizes itself to the size of
 * the browser viewport and manages window resizing. There may only be one Viewport created
 * in a page. Inner layouts are available by virtue of the fact that all {@link Ext.Panel Panel}s
 * added to the Viewport, either through its {@link #items}, or through the items, or the {@link #add}
 * method of any of its child Panels may themselves have a layout.</p>
 * <p>The Viewport does not provide scrolling, so child Panels within the Viewport should provide
 * for scrolling if needed using the {@link #autoScroll} config.</p>
 * <p>An example showing a classic application border layout:</p><pre><code>
new Ext.Viewport({
    layout: 'border',
    items: [{
        region: 'north',
        html: '&lt;h1 class="x-panel-header">Page Title&lt;/h1>',
        autoHeight: true,
        border: false,
        margins: '0 0 5 0'
    }, {
        region: 'west',
        collapsible: true,
        title: 'Navigation',
        width: 200
        // the west region might typically utilize a {@link Ext.tree.TreePanel TreePanel} or a Panel with {@link Ext.layout.AccordionLayout Accordion layout} 
    }, {
        region: 'south',
        title: 'Title for Panel',
        collapsible: true,
        html: 'Information goes here',
        split: true,
        height: 100,
        minHeight: 100
    }, {
        region: 'east',
        title: 'Title for the Grid Panel',
        collapsible: true,
        split: true,
        width: 200,
        xtype: 'grid',
        // remaining grid configuration not shown ...
        // notice that the GridPanel is added directly as the region
        // it is not "overnested" inside another Panel
    }, {
        region: 'center',
        xtype: 'tabpanel', // TabPanel itself has no title
        items: {
            title: 'Default Tab',
            html: 'The first tab\'s content. Others may be added dynamically'
        }
    }]
