This is really the same issue written here...
https://jira.appcelerator.org/browse/TIMOB-27328

I skirted the issue by switching to a fade-effect. But I think the downside of this PR removing the open animation is that if the app has a long startup time, then no open animation will occur when you open the 1st child window.

@lokeshchdhry, would you mind trying the below code. It blocks on app startup for 4 seconds before opening a window reading "Hello World". Verify that you see that an open-animation between the splash and the child window... because I think this PR has removed that animation.

function blockThread() {
	var endTime = new Date();
	endTime.setTime(endTime.getTime() + 4000);
	while (endTime >= new Date()) {}
}
blockThread();

var window = Ti.UI.createWindow();
window.add(Ti.UI.createLabel({ text: "Hello World!" }));
window.open();

@jquick-axway This shouldn't affect the animation of TiActivity windows. But I figured the fix should live in TiLaunchActivity instead (this won't affect the behavior of the fix). But you may want to re-test?

Looks like the latest force push missed some code or something.
