// TODO:
// 1) Perhaps make the borders sensitive to dragging in order to create a split.
//    The MFC splitter window manages scrollbars as well so is able to
//    put sash buttons on the scrollbars, but we probably don't want to go down
//    this path.
// 2) for wxWindows 2.0, we must find a way to set the WS_CLIPCHILDREN style
//    to prevent flickering. (WS_CLIPCHILDREN doesn't work in all cases so can't be
//    standard).
