[TIMOB-9191] iOS: Ti.UI.View backgroundLeftCap backgroundTopCap Broken on Retina Displays

var win = Ti.UI.createWindow({
    backgroundColor: '#fff'
});
// WORKS: buttons backgrounds stretch properly on Retina displays!
win.add(Ti.UI.createButton({
    top: 10, right: 10, left: 10,
    height: 30,
    // "search.png" is:
    // - On Non-Retina: 35x30
    // - On Retina: 70x60
    backgroundImage: 'search.png',
    // 35 / 2 = 17.5, so use 17, 34 pixels for the edges, with 1 pixel to repeat in the middle.
    backgroundLeftCap: 17
}));
// FAILS: ends up distorted on the left and right caps on Retina displays!
win.add(Ti.UI.createView({
    top: 50, right: 10, left: 10,
    height: 30,
    backgroundImage: 'search.png',
    backgroundLeftCap: 17
}));
win.open();
