Abdel, this shows that metrics computation is still very expensive on
mac. We might have to revise the policy of returning the width from
paint operation. Am I right that Painter::text should _either_ draw
text _or_ compute width? Are there cases where we need both?
I think there is single case in rowpainter that do both. I half expected
performance degradation on Mac (and I said that at the time) but I
wanted to be sure before taking any action. My plan was to change the
width() calculation in QLPainter::text() to use theFontMetrics() instead
if it shows as a problem on Mac. It is apparently, I'll do the change.
Also, we can probably use something better than a map (I'm sure qt has
nice hash tables) to store metrics.
Or Andre's vector solution. I'll check it out.
