I want to keep the 3rd-party packages away from the main source
where possible.

</span> * @class Ext.layout.FormLayout
* @extends Ext.layout.AnchorLayout
* &lt;p&gt;This layout manager is specifically designed for rendering and managing child Components of
* {@link Ext.form.FormPanel forms}. It is responsible for rendering the labels of
* {@link Ext.form.Field Field}s.&lt;/p&gt;
*
* &lt;p&gt;This layout manager is used when a Container is configured with the &lt;tt&gt;layout:'form'&lt;/tt&gt;
* {@link Ext.Container#layout layout} config option, and should generally not need to be created directly
* via the new keyword. See &lt;tt&gt;&lt;b&gt;{@link Ext.Container#layout}&lt;/b&gt;&lt;/tt&gt; for additional details.&lt;/p&gt;
*
* &lt;p&gt;In an application, it will usually be preferrable to use a {@link Ext.form.FormPanel FormPanel}
* (which is configured with FormLayout as its layout class by default) since it also provides built-in
* functionality for {@link Ext.form.BasicForm#doAction loading, validating and submitting} the form.&lt;/p&gt;
*
* &lt;p&gt;A {@link Ext.Container Container} &lt;i&gt;using&lt;/i&gt; the FormLayout layout manager (e.g.
* {@link Ext.form.FormPanel} or specifying &lt;tt&gt;layout:'form'&lt;/tt&gt;) can also accept the following
* layout-specific config properties:&lt;div class=&quot;mdetail-params&quot;&gt;&lt;ul&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.form.FormPanel#hideLabels hideLabels}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.form.FormPanel#labelAlign labelAlign}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.form.FormPanel#labelPad labelPad}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.form.FormPanel#labelSeparator labelSeparator}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.form.FormPanel#labelWidth labelWidth}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;/ul&gt;&lt;/div&gt;&lt;/p&gt;
*
* &lt;p&gt;Any Component (including Fields) managed by FormLayout accepts the following as a config option:
* &lt;div class=&quot;mdetail-params&quot;&gt;&lt;ul&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#anchor anchor}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;/ul&gt;&lt;/div&gt;&lt;/p&gt;
*
* &lt;p&gt;Any Component managed by FormLayout may be rendered as a form field (with an associated label) by
* configuring it with a non-null &lt;b&gt;&lt;tt&gt;{@link Ext.Component#fieldLabel fieldLabel}&lt;/tt&gt;&lt;/b&gt;. Components configured
* in this way may be configured with the following options which affect the way the FormLayout renders them:
* &lt;div class=&quot;mdetail-params&quot;&gt;&lt;ul&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#clearCls clearCls}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#fieldLabel fieldLabel}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#hideLabel hideLabel}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#itemCls itemCls}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#labelSeparator labelSeparator}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;li&gt;&lt;b&gt;&lt;tt&gt;{@link Ext.Component#labelStyle labelStyle}&lt;/tt&gt;&lt;/b&gt;&lt;/li&gt;
* &lt;/ul&gt;&lt;/div&gt;&lt;/p&gt;
*
* &lt;p&gt;Example usage:&lt;/p&gt;
* &lt;pre&gt;&lt;code&gt;
