[ros-diffs] [navaraf] 17928: - Move the window showing/hiding notifications from co_WinPosShowWindow to co_WinPosSetWindowPos and fix up the top-level checks.

- Move the window showing/hiding notifications from co_WinPosShowWindow
to co_WinPosSetWindowPos and fix up the top-level checks.
- Call the redraw routine on parent window if possible in
co_WinPosSetWindowPos. Should fix bug #735.
