Window.wasResized() always returns false

[AlexanderJCS]

I noticed that Window.wasResized() always returns false, even when the window was resized. To check for a resized window, I had to come up with this workaround:

// Since Window.wasResized() always evaluates to false this is my workaround

if (this.windowSize == null) {
    this.windowSize = Window.getWindowSize();
}

if (this.windowSize.equals(Window.getWindowSize())) {
    return;
}

I'm not sure why Window exhibits this behavior since Window.getWindowSize() is updated correctly.
