Pinch zoom scroll touch

Simple code that allows multitouch and single touch on an image.
In my project I added lots of assets on top of the image and put them all in a container. This allowed me move a chart (map) and overlay marks and routes and have them all zoom, pinch and scroll.

Works with Corona build #:
