Getting a chunk of stylized text?

[Dan Friedman]

Fellow Revolutionaries,

Let's say field A contains more text than can fit in it.  The text in field
A contains multiple fonts, styles and sizes.  How can I get the stylized
text that is not being displayed? (and remove it from field A and put it
into field B)

I tried messing with the formattedHeight and formattedLines functions, but I
can't seem to get it to find the correct text.  What I think I need to do,
some how, is get the formattedTop of a line of the formattedText.  But you
can't do that.

Any thoughts?

Thank you in advance,
Dan
