OK, these numbers seem OK. Let us try this:

void MultiButton::Paint(Draw& w)
{
	Size sz = GetSize();
	int border, lx, rx;
	bool frm = Metrics(border, lx, rx);
	int mst = ChState(MAIN);
	if(frm)
		ChPaint(w, sz, style->edge[style->activeedge ? mst : 0]);
	bool left = false;
	bool right = false;
	for(int i = 0; i < button.GetCount(); i++) {
		SubButton& b = button[i];
		int st = ChState(i);
		int x = 0, cx = 0;
		GetPos(b, lx, rx, x, cx);
		bool dopaint = true;
		Value v = b.left ? left ? style->lmiddle[st] : style->left[st]
		                 : right ? style->rmiddle[st] : style->right[st];
		if(ComplexFrame())
			ChPaint(w, x, border, cx, sz.cy - 2 * border, style->simple[st]);
		else
		if(frm) {
			if(IsTrivial() && style->usetrivial)
				dopaint = false;
			ChPaint(w, x, border, cx, sz.cy - 2 * border,
			        dopaint ? v : style->trivial[st]);
		}
		else {
			w.Clip(x, 0, cx, sz.cy);
			ChPaint(w, sz, style->look[Frame() ? mst : st]);
			if(IsNull(v) || !Frame()) {
				if((!IsTrivial() || style->trivialsep) && IsEnabled()) {
					if(b.left) {
						if(left)
							ChPaint(w, x, style->sepm, 1, sz.cy - 2 * style->sepm, style->sep1);
						ChPaint(w, x + cx - 1, style->sepm, 1, sz.cy - 2 * style->sepm, style->sep2);

				}
			}
			else
				ChPaint(w, x, 0, cx, sz.cy, v);
			w.End();
		}
		if(dopaint) {
			Size tsz = GetTextSize(b.label, StdFont());



			Image m = tsz.cx > 0 ? b.img : (Image)Nvl(b.img, CtrlsImg::DA());
			Size isz = m.GetSize();

			Point p = (st == CTRL_PRESSED) * style->pressoffset;
			p.x += x + (cx - isz.cx - tsz.cx - (tsz.cx > 0 && isz.cx > 0 ? LB_IMAGE : 0)) / 2;
			p.y += (sz.cy - isz.cy) / 2;
			if(b.left) {
				if(!left) p.x += style->loff;
			}
			else
				if(!right) p.x += style->roff;
			if(b.monoimg || IsNull(b.img))
				w.DrawImage(p.x, p.y, m, frm ? style->fmonocolor[st] : style->monocolor[st]);
			else
				w.DrawImage(p.x, p.y, m);

DDUMP(tsz);
DDUMP(isz);
DDUMP(sz);
DDUMP((sz.cy - tsz.cy) / 2);
			if(tsz.cx > 0) {
				if(isz.cx > 0)
					p.x += isz.cx + LB_IMAGE;
				w.DrawText(p.x, (sz.cy - tsz.cy) / 2, b.label);
			}
		}
		(b.left ? left : right) = true;
	}
	Rect r, cr;
	Color text = SColorLabel();
	Color paper = Null;
	if(ComplexFrame()) {
		cr = GetSize();
		cr.left = lx;
		cr.right = rx;

	}
	else
	if(frm) {
		Rect m = style->margin;
		r = Rect(max(lx, m.left), m.top, min(rx, sz.cx - m.right), sz.cy - m.bottom);
		Color paper;
		if(mst == CTRL_HOT && !IsTrivial())

		else
		if(mst == CTRL_PRESSED && !IsTrivial())
			paper = Blend(SColorHighlight, SColorFace, 235);
		else

			}
		}
		w.End();
		cr = r;
	}
	cr.left++;
	Rect clr = cr;
	if(!IsNull(valuecy)) {
		cr.top += (cr.GetHeight() - valuecy + 1) / 2;
		cr.bottom = cr.top + valuecy;
	}
	Value v = convert->Format(value);
	bool f = HasFocus() && !push && frm;
	if(cr.left < cr.right && display) {
		w.Clip(clr);
		display->Paint(w, cr, v,
		               IsShowEnabled() ? text : SColorDisabled,
		               paper, f ? Display::CURSOR : Display::FOCUS|Display::CURSOR);
		w.End();
	}
	if(!frm && HasFocus())
		DrawFocus(w, r);
}


(It is in CtrlLib/MultiButton.cpp).
