One thing to realize is that text editors like Emacs or vi are
_really fast_. They generally don't actually lay out the text,
and instead simply count lines, or (for Emacs) characters, when
setting up the scrollbars.

Because GtkTextView handles styled text, and because it displays
pixel-based scrollbars, it will never be as fast as that sort
of text editor.
