[TIMOB-14506] TiAPI: Label auto-size behavior different on Android / iOS

A label's auto-size behavior different on Android / iOS. iOS has the expected behavior. On android, when the label's width shrinks and the text is word-wrapped, the label's width doesn't match what is displayed on screen when the word-wrapping results in a smaller width that the width change that caused the word-wrapping. I know that's a mouthful, but hopefully the code below will make it clear why android is broken. Clicking the label will alert with the current vwScreen.width and label.width, then shrink the vwScreen.width by 5%. So as you click the label multiple times, the label will start to word wrap. When you run the code below on iOS iPhone 5 simulator and click the label, you'll see the first three values are: vwScreen.width, label.width 320, 310 304, 194 304, 194 The point here is that the label's width is exactly the width of the text. On Android, the same word-wrapping happens correctly, but the label's width property remains larger, always equal to the containing view. The first three values on my Android emulator are: 480, 480 456, 456 433, 433 I have labels that I want to horizontally center, and because of this bug I cannot do so on android.

var isIOS = (Ti.Platform.name === 'iPhone OS');

var window = Ti.UI.createWindow({
	fullScreen : false,
	title : 'Label Auto Size Bug',
	backgroundColor : 'white',
	modal : true,
	exitOnClose : true,
	navBarHidden : true
});

var vwScreen = Ti.UI.createView({
	left : 0,
	top : 0,
	width : Ti.Platform.displayCaps.platformWidth,
	height : Ti.Platform.displayCaps.platformHeight,
	backgroundColor: "#FF0000"
});
window.add(vwScreen);

var lblInfo = Ti.UI.createLabel({
	color : 'white',
	left : 0,
	top : 100,
	height : Ti.UI.SIZE,
	width : Ti.UI.SIZE,
	backgroundColor: "#0000FF",
	text : '4112 N HIGH SCHOOL RD, INDIANAPOLIS, IN',
	font : {
		fontSize : isIOS ? 15 : 35,
		fontWeight : 'bold'
	}
});

lblInfo.addEventListener('click', function() {
	alert('vwScreen.rect.width = ' + vwScreen.rect.width + ' lblInfo.rect.width = ' + lblInfo.rect.width);
	vwScreen.width = vwScreen.rect.width * 0.95;
});

vwScreen.add(lblInfo);
window.open();
