I know about the inaccuracy of the getTextHeight(graphics2d) method, which 
varies from Windows/Linux/Mac system and the way Java vs. Windows-GDI renders 
fonts. You can test the height calculation of various RTF stylings by rendering 
the PNG via PPTX2PNG and check it against the output of Powerpoint.

If the result satisfies you *), then you are able to figure out of the point of 
text overflow, which occurs when getTextHeight() is longer than your original 
textbox ...
what exactly confuses you when you compare those two values?

*) If the result doesn't satisfy you, then you need to dig into the SL Common 
drawing classes, and optimize the text rendering to your runtime environment 
and used fonts, which you probably don't know beforehand ...
