/** - * Perform custom animation on this element. - *

Animation Properties

The Animation Control Object enables gradual transitions for any member of an - * element's style object that takes a numeric value including but not limited to - * these properties:

bottom, top, left, right
height, width
margin, padding
borderWidth
opacity
fontSize
lineHeight

Animation Property Attributes

Each Animation Property is a config object with optional properties:

by* : relative change - start at current value, change by this value
from : ignore current value, start from this value
to* : start at current value, go to this value
unit : any allowable unit specification

* do not specify both to and by for an animation property

Animation Types

The supported animation types:

'run' : Default - *


-var el = Ext.get('complexEl');
-el.animate(
-    // animation control object
-    {
-        borderWidth: {to: 3, from: 0},
-        opacity: {to: .3, from: 1},
-        height: {to: 50, from: el.getHeight()},
-        width: {to: 300, from: el.getWidth()},
-        top  : {by: - 100, unit: 'px'},
-    },
-    0.35,      // animation duration
-    null,      // callback
-    'easeOut', // easing method
-    'run'      // animation type ('run','color','motion','scroll')    
-);
-         *

- *

'color' - *

Animates transition of background, text, or border colors.

- *


-el.animate(
-    // animation control object
-    {
-        color: { to: '#06e' },
-        backgroundColor: { to: '#e06' }
-    },
-    0.35,      // animation duration
-    null,      // callback
-    'easeOut', // easing method
-    'color'    // animation type ('run','color','motion','scroll')    
-);
-         *

- *

'motion' - *

Animates the motion of an element to/from specific points using optional bezier - * way points during transit.

- *


-el.animate(
-    // animation control object
-    {
-        borderWidth: {to: 3, from: 0},
-        opacity: {to: .3, from: 1},
-        height: {to: 50, from: el.getHeight()},
-        width: {to: 300, from: el.getWidth()},
-        top  : {by: - 100, unit: 'px'},
-        points: {
-            to: [50, 100],  // go to this point
-            control: [      // optional bezier way points
-                [ 600, 800],
-                [-100, 200]
-            ]
-        }
-    },
-    3000,      // animation duration (milliseconds!)
-    null,      // callback
-    'easeOut', // easing method
-    'motion'   // animation type ('run','color','motion','scroll')    
-);
-         *

- *

'scroll' - *

Animate horizontal or vertical scrolling of an overflowing page element.

- *


-el.animate(
-    // animation control object
-    {
-        scroll: {to: [400, 300]}
-    },
