Extends dojo/_base/fx.animateProperty to animate a "complex property". The primary example is the clip style: rect(10px 30px 10px 50px). Note this can also be used with (and is actually intended for) CSS3 properties, such as transform: transform: rotate(10deg) translateX(0px)
The standard animation doesn't know what to do with something like rect(...). This class identifies complex properties by they being a string and having parenthesis. If so, that property is made into a dojox.fx._Complex object and the getValue() is obtained from there.
See the dojox/fx/ext-dojo/complex reference documentation for more information.
var ani = dojo.animateProperty({
node:dojo.byId("myDiv"),
duration:600,
properties:{
clip:{start:'rect(0px 50px 50px 0px)', end:'rect(10px 30px 30px 10px)'}
}
}).play();
