[Bug 51194] Unity games on Mac are not correctly foregrounded on launch

--- Comment #1 from Brendan Shanks  ---
Additionally, the window does get correctly foregrounded without a Sleep() or
additional SetWindowPos() call.

This appears to be luck: without any extra time after the SetWindowPos() call,
the window has not had any time to be shown (and the
applicationWill/DidBecomeActive / APP_ACTIVATED events sent). When SetFocus()
is called, the app isn't active, so makeKeyWindow: doesn't take effect
immediately.
windowDidBecomeKey: is called later, not under the call stack of makeFocused: /
makeKeyWindow:, so the logic in those commits doesn't apply.
