Some applications depend on the fact that WM_WINDOWPOSCHANGING is sent after WM_SHOWWINDOW when SetParent is called, even if the window ends up not visible because its parent is not visible, and occurs when the window itself does not have the WS_CHILD style set.
This also fixes a TODO message sequence, so that Wine matches Windows.
