Line wrapping isn't hard - call FntWordWrap after setting the font,
and use it to walk through the text that you need to wrap/draw.
You'll have to be responsible for figuring out when the font changes,
and to what, of course.
Scrolling gets a bit harder. If you don't have much text, then the
easy thing to do is to always re-wrap from the start of the text,
until you reach the first displayable line. After that you continue
with your normal wrap/draw code. So assuming you've got a bounding
rectangle and your text/font run info, then the only other two pieces
of info you'll need are the scroll amount (number of lines "above"
the top of your bounding rect) and the byte offset to the first
displayable line.
