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. <br /><br />The zoom and rotate events are triggered when at least two fingers are detected. <br /><br />This code isn't optimized and run on both IOS and android. <br /><br />Note that the transformations are handled only through javascript and math computations, the tablet operating system inbuilt functions are disabled by script.
