This routine sets the ScrollEndPad, which is the amount of padding added to
both ends of the scrollbars when they are displayed. When arrows are
displayed (see flag SBWF_ARROWS), the actual pad value will be the greater
of: the value set by IWidget_SetScrollEndPad(), and the length of the
scrollbar arrows. In other words, the pad will be such that the scrollbar
rectangles will never overlap the scrollbar arrow glyphs.
int IWidget_SetScrollEndPad(IWidget *pif, int nPad);
AEE_SUCCESS - If the widget is able to set scrollendpad value.
AEE_EFAILED - If the widget failed to set scrollendpad value.
