/**
 * @class Ext.Fx
 *

A class to provide basic animation and visual effects support.  Note: This class is automatically applied
 * to the {@link Ext.Element} interface when included, so all effects calls should be performed via {@link Ext.Element}.
 * Conversely, since the effects are not actually defined in {@link Ext.Element}, Ext.Fx
must be
 * {@link Ext#enableFx included} in order for the Element effects to work.



 *
 *

Method Chaining


 *

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
{@link #callback}.



 *
 *

Anchor Options for Motion Effects


 *

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:


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

 *
Note: some Fx methods accept specific custom config parameters.  The options shown in the Config Options
 * section below are common options that can be passed to any Fx method unless otherwise noted.
 *
 * @cfg {Function} callback A function called when the effect is finished.  Note that effects are queued internally by the
 * Fx class, so a callback is not required to specify another effect -- effects can simply be chained together
 * and called in sequence (see note for
Method Chaining above), for example:

 * el.slideIn().highlight();
 *

 * The callback is intended for any additional code that should run once a particular effect has completed. The Element
 * being operated upon is passed as the first parameter.
 *
 * @cfg {Object} scope The scope of the
{@link #callback} function
 *
 * @cfg {String} easing A valid Ext.lib.Easing value for the effect:


 *
 * @cfg {String} afterCls A css class to apply after the effect
 * @cfg {Number} duration The length of time (in seconds) that the effect should last
 *
 * @cfg {Number} endOpacity Only applicable for {@link #fadeIn} or {@link #fadeOut}, a number between
 *
0 and 1 inclusive to configure the ending opacity value.
 *  
 * @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
 * @cfg {Boolean} useDisplay Whether to use the
display CSS property instead of visibility when hiding Elements (only applies to
 * effects that end with the element being visually hidden, ignored otherwise)
 * @cfg {String/Object/Function} afterStyle A style specification string, e.g.
"width:100px", or an object
 * in the form
{width:"100px"}, or a function which returns such a specification that will be applied to the
 * Element after the effect finishes.
 * @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
 * @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
 * @cfg {Boolean} stopFx Whether preceding effects should be stopped and removed before running current effect (only applies to non blocking effects)
