To and fro Maximize and FullScreen mode transitions detours through or stop at WindowNoState/NormalMode state.

Issue 1:

Environments: OS X 10.8.1, Windows 7

Description
When maximized and fullscreen requested, the window transitions to normal before entering fullscreen.

Steps to reproduce the issue:

1. Launch fullscreentest_v1.zip test program.
2. Click the "Maximized" button.
3. Click the "FullScreen" button.

Result
The application window is set to normal mode and then changes to fullscreen mode. This is also noticeable in the Application Output window as the application logs all window state changes (0 = Normal, 2 = Maximized, and 4 = FullScreen). On OS X, the problem is clearly visible in the sample application. On Windows, the problem is only visible for complex QML applications.

Expected Result
The application window would be set to fullscreen mode without being set to normal mode.
