Added DW_FCF_COMPOSITED frame creation flag, used only on Windows currently... it enabled composited (translucent) windows on supported versions of Windows (7 and Vista). Deprecated the DW_FCF_VERTSCROLL and DW_FCF_HORZSCROLL flags... use scrollboxes instead. Removed a terrible hack of using the WS_VSCROLL flag to pass task list... applications require a recompile so we will still handle the old WS_VSCROLL flag until version 3.
