Is it possible to refactor StdDisplayClass::Paint0() to make drawing of truncated strings a separate function?
This is needed very often when making your own Display classes.

At this time I'm using copy-pasted simplified code from StdDisplayClass::Paint0() which looks like below.

	{
		WString txt;
		Font font = StdFont();
		int x = r.left;
		int width = r.GetWidth();
		txt = StdConvert().Format(offset);
		Size tsz = GetTLTextSize(txt, font);
		int tcy = GetTLTextHeight(txt, font);
		int tt = r.top + max((r.Height() - tcy) / 2, 0);
		if(tsz.cx > width) {
			Size isz = DrawImg::threedots().GetSize();
			int wd = width - isz.cx;
			w.Clip(r.left, r.top, wd, r.GetHeight());
			DrawTLText(w, x, tt, width, txt, font, ink);
			w.End();
			w.DrawImage(r.left + wd, tt + font.Info().GetAscent() - isz.cy, DrawImg::threedots(), ink);
		}
		else
			DrawTLText(w, x, tt, width, txt, font, ink);
	}

IMHO, it would be useful to have a reusable and supported function for such common functionality.

Thanks.
