Returns the <a class="link" href="GtkTextBuffer.html" title="GtkTextBuffer"><span class="type">GtkTextBuffer</span></a> being displayed by this text view.
The reference count on the buffer is not incremented; the caller
of this function won't own a new reference.</p>

Note that this function uses the currently-computed height of the
lines in the text buffer. Line heights are computed in an idle 
handler; so this function may not have the desired effect if it's 
called before the height computations. To avoid oddness, consider 
using <a class="link" href="GtkTextView.html#gtk-text-view-scroll-to-mark"><code class="function">gtk_text_view_scroll_to_mark()</code></a> which saves a point to be 
scrolled to after line validation.</p>
