Custom iOS XappyShellRenderer broke in 4.3

[anotherlab]

I just started seeing this on iOS when I updated from XF 4.2 to XF 4.3. If you compile Xappy with XF 4.3, the flyout view bounds in XappyShellRenderer.OnFlyoutWillAppear are for the full screen, not for the width of the flyout. When the flyout is closed, you see the right edge of the gradient view

When you invoke the flyout, the gradient view is full screen width.
