[tkreuzer] 27394: co_WinPosSetWindowPos: fix the redrawing (instead of simply removing some code, like my last commit, sorry). Now it works more like on windows and both the problem of a blank control panel and ugly wizard pages are gone. Fixes bug 735, see also bug 902, may fix bug 2141. See issue #735 for more details.
