[Qt-interest] QGraphicsTextItem adjustSize()

[Stacy Alley]

Thanks Sean.   Good idea.  I need to start simple.
I did try outputting the scale factors and it turns out the scale factor 
is one.  So
there is now wonder I'm not seeing an improvement.  So I'll take your 
suggestion
and write a simple example to figure out where I'm going wrong.
Thanks again!
