Removed the plotText function and replaced it with the DiveTextItem class - this way there's just one way to add text on screen, and it also makes it easy to fix positioning of stuff there. Which is what I'll try to fix on the next commit. Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
