* Takes an array of objects and returns the last element in the array that has properties which match
|
|
|
|
* all of those specified in the `compare` object. For example, if the compare object was: `{ scaleX: 0.5, alpha: 1 }`
|
|
|
|
* then it would return the last item which had the property `scaleX` set to 0.5 and `alpha` set to 1.
