HTML 5 Canvas - Multitouch events : Zoom and Rotate

A simple showcase application to show what can be done while playing with both HTML 5 canvas and tablets multitouch events.

The zoom and rotate events are triggered when at least two fingers are detected.

This code isn't optimized and run on both IOS and android.

Note that the transformations are handled only through javascript and math computations, the tablet operating system inbuilt functions are disabled by script.
