[TIMOB-17593] iOS: Labels not layed out correctly on toImage()

Problem Description

In 3.3.0.GA all labels disappears when I do toImage() on their container view. This worked perfectly fine in all versions before 3.3.0.GA (try 3.2.3.GA for instance). This toImage()-approach is very useful to build images of the gui instead of having components (such as labels) rendered all the time. It makes the UI much snappier/performant and I use it alot. This is a complete stopper for me.

Sample Code

Titanium.UI.setBackgroundColor('#000');
var view= require('FirstView');
var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});
win1.add(view());
win1.open();

function FirstView() {
 
    var buildView = Ti.UI.createView({
        backgroundColor:'red',
        width:100,
        height:100
    });
 
    buildView.add(Ti.UI.createLabel({
        backgroundColor:'yellow',
        color:'#000000',
        text:'ABC',
    }));
     
    var container = Ti.UI.createView({
        width:100,
        height:100,
        backgroundImage: buildView.toImage()
    });
 
    return container;
}
module.exports = FirstView;

Steps to reproduce

- Create a new Project. - Copy the "app.js" code to the project "app.js" file. - Create a new file named "FirstView" in Projects Resource directory. - Copy the "FirstView.js" code to the project "FirstView.js" file. - Run the Project.

Actual results

OBSERVED PROBLEM In SDK version 3.2.3.GA the label is shown where in SDK version 3.3.0.GA the label despaired. view.toImage() is not working in New SDK 3.3.0.GA
