If ScrollWindowEx is called with SW_SCROLLCHILDREN flags for a window with a WS_CLIPCHILDREN style, then do not use the DCX_USESTYLE flag option to get a DC for this window. With a couple of regression tests.
DCX_USESTYLE has other effects, is it really correct to disable them all? And if so, wouldn't it be better to never use DCX_USESTYLE?
