[gtkmm] "Autoscrolling" TextView

[Christer Palm <palm nogui se>]

Hi!

Does anyone have a smart way to make a scrolled TextView scroll along as 
text is inserted - if, and only if the TextView is showing the bottom 
part of the buffer?

I can't find an elegant way to determine whether the TextView is "at the 
bottom" of the buffer, and to handle the situation when resizing an 
autowrap TextView causes the last line to split, which in turn causes it 
to drop out of the bottom position.
