MouseWheel for control fires multipule times

[Shadowblitz16]

MouseWheel fires multiple times for control making scrolling 1 notch impossible.

This seems to fix it...

    protected override void OnMouseWheel(MouseEventArgs e)
    {
        base.OnMouseWheel(e);

        _wheelLock = !_wheelLock;
        if (_wheelLock) return;
        if      (e.Delta < 0) ViewZoom  = long.Clamp(ViewZoom-1, 1, 8);
        else if (e.Delta > 0) ViewZoom  = long.Clamp(ViewZoom+1, 1, 8);
        Invalidate();
    }
