-to the <a href="output/Ext.Element.html" ext:cls="Ext.Element">Ext.Element</a> interface when included, so all effects calls should be performed via <a href="output/Ext.Element.html" ext:cls="Ext.Element">Ext.Element</a>.
-Conversely, since the effects are not actually defined in <a href="output/Ext.Element.html" ext:cls="Ext.Element">Ext.Element</a>, Ext.Fx <b>must</b> be

-<p><b><u>Method Chaining</u></b></p>
-<p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
-they return the Element object itself as the method return value, it is not always possible to mix the two in a single
-method chain.  The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
-Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately.  For this reason,
-while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
-expected results and should be done with care.  Also see <tt><a href="output/Ext.Fx.html#Ext.Fx-callback" ext:member="callback" ext:cls="Ext.Fx">callback</a></tt>.</p><br/>
-<p><b><u>Anchor Options for Motion Effects</u></b></p>
-<p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
-that will serve as either the start or end point of the animation.  Following are all of the supported anchor positions:</p>
-<pre>
-Value  Description
------  -----------------------------
-tl     The top left corner
-t      The center of the top edge
-tr     The top right corner
-l      The center of the left edge
-r      The center of the right edge
-bl     The bottom left corner
-b      The center of the bottom edge
-br     The bottom right corner
-</pre>

+<p><b><u>Method Chaining</u></b></p>
+<p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
+they return the Element object itself as the method return value, it is not always possible to mix the two in a single
+method chain.  The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
+Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately.  For this reason,
+while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
+expected results and should be done with care.  Also see <tt><a href="output/Ext.Fx.html#Ext.Fx-callback" ext:member="callback" ext:cls="Ext.Fx">callback</a></tt>.</p><br/>
+<p><b><u>Anchor Options for Motion Effects</u></b></p>
+<p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
+that will serve as either the start or end point of the animation.  Following are all of the supported anchor positions:</p>
+<pre>

+t      The center of the top edge
