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. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
