Profile: make sure text is scaled correctly when drawn

We had all this wonderful code to scale the text correctly, except we went
out of our way to make sure the code wouldn't be called unless something
changed on this specific text item. But that's bogus because the scaling
depends on external factors like the fontPrintScale.

So instead of calling updateText() when attributes of this DiveTextItem
change simply call it right before the DiveTextItem gets painted.
