[TIMOB-2390] Android: Image views where height is set very small can result in java.lang.ArithmeticException (divide by zero)

failcase app.js, wherein we set the height to 1:

Titanium.UI.setBackgroundColor('#000');
var w = Titanium.UI.createWindow({  
    title:'Test',
    backgroundColor:'#fff',
    fullscreen: true,
    exitOnClose: true
});
w.open();
w.add( Ti.UI.createImageView({
    width: 1,
    height: 1,
    image: 'http://www.appcelerator.com/wp-content/uploads/2009/06/titanium_desk.png'
}) );
