Android Image Rotation within a webview for builtin Pinch zoom

app.js

var win = Ti.UI.createWindow();

var web = Ti.UI.createWebView({
	html:'<img src="test.jpg"/>',
	//url:'http://appcelerator.com'
});

win.add(web);

var button = Ti.UI.createButton({
	width:50,
	height:50,
	bottom:10,
	left:10
});

win.add(button);

button.addEventListener('click', function(){

		web.animate({opacity:0.5, duration:500});
		web.opacity = 0.5;
		var start = 0;
		web.addEventListener('touchstart', function(e){
			start = e.x;
		})
	
	web.addEventListener('touchmove', function(e){
		var point = ((360/Ti.Platform.displayCaps.platformWidth)*(e.x-start))/2;
		Ti.API.info(point);
		Ti.API.info(e.x);
		
		var t = Ti.UI.create2DMatrix();
		t = t.rotate(point);

		web.transform=t;
	});
	
});

win.open();

This is a work in progress to make a swipe to rotate functionality. Any suggestions are welcome.
