/**
+ * @class Ext.util.Animate
+ * This animation class is a mixin.
+ * 
+ * Ext.util.Animate provides an API for the creation of animated transitions of properties and styles.  
+ * This class is used as a mixin and currently applied to {@link Ext.core.Element}, {@link Ext.CompositeElement}, 
+ * {@link Ext.draw.Sprite}, {@link Ext.draw.CompositeSprite}, and {@link Ext.Component}.  Note that Components 
+ * have a limited subset of what attributes can be animated such as top, left, x, y, height, width, and 
+ * opacity (color, paddings, and margins can not be animated).
+ * 
+ * ## Animation Basics
+ * 
+ * All animations require three things - `easing`, `duration`, and `to` (the final end value for each property) 
+ * you wish to animate. Easing and duration are defaulted values specified below.
+ * Easing describes how the intermediate values used during a transition will be calculated. 
+ * {@link Ext.fx.Anim#easing Easing} allows for a transition to change speed over its duration.
+ * You may use the defaults for easing and duration, but you must always set a 
+ * {@link Ext.fx.Anim#to to} property which is the end value for all animations.  
+ * 
+ * Popular element 'to' configurations are:
+ * 
+ *  - opacity
+ *  - x
+ *  - y
+ *  - color
+ *  - height
+ *  - width 
+ * 
+ * Popular sprite 'to' configurations are:
+ * 
+ *  - translation
+ *  - path
+ *  - scale
+ *  - stroke
+ *  - rotation
+ * 
+ * The default duration for animations is 250 (which is a 1/4 of a second).  Duration is denoted in 
+ * milliseconds.  Therefore 1 second is 1000, 1 minute would be 60000, and so on. The default easing curve 
+ * used for all animations is 'ease'.  Popular easing functions are included and can be found in {@link Ext.fx.Anim#easing Easing}.
+ * 
+ * For example, a simple animation to fade out an element with a default easing and duration:
+ * 
+ *     var p1 = Ext.get('myElementId');
+ * 
+ *     p1.animate({
+ *         to: {
+ *             opacity: 0
+ *         }
+ *     });
+ * 
+ * To make this animation fade out in a tenth of a second:
+ * 
+ *     var p1 = Ext.get('myElementId');
+ * 
+ *     p1.animate({
+ *        duration: 100,
+ *         to: {
+ *             opacity: 0
+ *         }
+ *     });
+ * 
+ * ## Animation Queues
+ * 
+ * By default all animations are added to a queue which allows for animation via a chain-style API.
+ * For example, the following code will queue 4 animations which occur sequentially (one right after the other):
+ * 
+ *     p1.animate({
+ *         to: {
+ *             x: 500
+ *         }
+ *     }).animate({
+ *         to: {
+ *             y: 150
+ *         }
+ *     }).animate({
+ *         to: {
+ *             backgroundColor: '#f00'  //red
+ *         }
+ *     }).animate({
+ *         to: {
+ *             opacity: 0
+ *         }
+ *     });
+ * 
+ * You can change this behavior by calling the {@link Ext.util.Animate#syncFx syncFx} method and all 
+ * subsequent animations for the specified target will be run concurrently (at the same time).
+ * 
+ *     p1.syncFx();  //this will make all animations run at the same time
+ * 
+ *     p1.animate({
+ *         to: {
+ *             x: 500
+ *         }
+ *     }).animate({
+ *         to: {
+ *             y: 150
+ *         }
+ *     }).animate({
+ *         to: {
+ *             backgroundColor: '#f00'  //red
+ *         }
+ *     }).animate({
+ *         to: {
+ *             opacity: 0
+ *         }
+ *     });
+ * 
+ * This works the same as:
+ * 
+ *     p1.animate({
+ *         to: {
+ *             x: 500,
+ *             y: 150,
+ *             backgroundColor: '#f00'  //red
+ *             opacity: 0
+ *         }
+ *     });
+ * 
+ * The {@link Ext.util.Animate#stopAnimation stopAnimation} method can be used to stop any 
+ * currently running animations and clear any queued animations. 
+ * 
+ * ## Animation Keyframes
+ *
+ * You can also set up complex animations with {@link Ext.fx.Anim#keyframe keyframe} which follows the 
+ * CSS3 Animation configuration pattern. Note rotation, translation, and scaling can only be done for sprites. 
+ * The previous example can be written with the following syntax:
+ * 
+ *     p1.animate({
+ *         duration: 1000,  //one second total
+ *         keyframes: {
+ *             25: {     //from 0 to 250ms (25%)
+ *                 x: 0
+ *             },
+ *             50: {   //from 250ms to 500ms (50%)
+ *                 y: 0
+ *             },
+ *             75: {  //from 500ms to 750ms (75%)
+ *                 backgroundColor: '#f00'  //red
+ *             },
+ *             100: {  //from 750ms to 1sec
+ *                 opacity: 0
+ *             }
+ *         }
+ *     });
+ * 
+ * ## Animation Events
+ * 
+ * Each animation you create has events for {@link Ext.fx.Anim#beforeanimation beforeanimation}, 
+ * {@link Ext.fx.Anim#afteranimate afteranimate}, and {@link Ext.fx.Anim#lastframe lastframe}.  
+ * Keyframed animations adds an additional {@link Ext.fx.Animator#keyframe keyframe} event which 
+ * fires for each keyframe in your animation.
+ * 
+ * All animations support the {@link Ext.util.Observable#listeners listeners} configuration to attact functions to these events.
+ *    
+ *     startAnimate: function() {
+ *         var p1 = Ext.get('myElementId');
+ *         p1.animate({
+ *            duration: 100,
+ *             to: {
+ *                 opacity: 0
+ *             },
+ *             listeners: {
+ *                 beforeanimate:  function() {
+ *                     // Execute my custom method before the animation
+ *                     this.myBeforeAnimateFn();
+ *                 },
+ *                 afteranimate: function() {
+ *                     // Execute my custom method after the animation
+ *                     this.myAfterAnimateFn();
+ *                 },
+ *                 scope: this
+ *         });
+ *     },
+ *     myBeforeAnimateFn: function() {
+ *       // My custom logic
+ *     },
+ *     myAfterAnimateFn: function() {
+ *       // My custom logic
+ *     }
+ * 
+ * Due to the fact that animations run asynchronously, you can determine if an animation is currently 
+ * running on any target by using the {@link Ext.util.Animate#getActiveAnimation getActiveAnimation} 
+ * method.  This method will return false if there are no active animations or return the currently 
+ * running {@link Ext.fx.Anim} instance.
+ * 
+ * In this example, we're going to wait for the current animation to finish, then stop any other 
+ * queued animations before we fade our element's opacity to 0:
+ * 
+ *     var curAnim = p1.getActiveAnimation();
+ *     if (curAnim) {
+ *         curAnim.on('afteranimate', function() {
+ *             p1.stopAnimation();
+ *             p1.animate({
+ *                 to: {
+ *                     opacity: 0
+ *                 }
+ *             });
+ *         });
+ *     }

+     * <p>For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:</p>

+    width: 500,
+    height: 300,
+    layout: {

+     * <p>For performance reasons, by default, the internal layout is only updated when the Window reaches its final <code>"to"</code> size. If dynamic updating of the Window's child
+     * Components is required, then configure the animation with <code>dynamic: true</code> and the two child items will maintain their proportions during the animation.</p>
