Touch pinch event also triggers rotation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Pinch using jsc3d touch

What is the expected output? What do you see instead?
Pinch should just zoom, not also trigger rotate event

What version of the product are you using? On what operating system?
Cordova + jsc3d + jsc3d touch + HTC One (Android)

Touch support in Jsc3d is built upon hammer.js's touch event mechanism. 
Pinching uses 'pinch' event while rotation is based on 'drag' event. Basically 
both should not be triggered at the same time. However, there may still be 
compatibility issues in hammer.js on different platforms, some of which are 
reported here: https://github.com/EightMedia/hammer.js/wiki/Compatibility. 
Could you help me to check it referring to that table?

I can reproduce on Iphone 5s on Safari as well as Ipad 3 with Safari, the 
rotation event happens about 80% of the time when lifting fingers after a zoom 
in gesture.

Thanks, Adam! I guess the unexpected rotation is trigered when one finger has 
leaved the touch device while the other still stays on it sliding. This has 
been fixed in r275 http://code.google.com/p/jsc3d/source/detail?r=257. The 
latest editon in the svn repository works without this issue.
