How to set aspect ratio options for Image Dialog

I have a requiment to create a new Aspect Ratio for image crop, besides the only default option of Free Crop

I understand that there was some path where you could set this up in CRX, prior to 5.5, but that path doesn't exist in 5.5. The path was /libs/cq/packaging/components/pack/definition/dialog/items/tabs/item s/tab3/cropConfig

I found this out from this forum question:http://forums.adobe.com/message/4575600#4575600

Where in CQ5.5 Can I set these aspect ratios? I've queried the entire CRX for nodes of similar names as in this path, but cannot find it anywhere.

Thanks guys!
