OutputDevice::GetTextWidth() That's fun :-) That in turn is called from SvLBox::RecalcViewData - which is called 11 times (seems odd), from SvTreeListBox::SetFont - which is called 9x times (odd). That is called from SvTreeListBox::PaintEntry1 - which is called 80x times - so, perhaps if we can work out what's up with changing the font there, we could get a 10x speedup of that piece. I've easy-hackified this, hopefully that'll increase interest.
