<p>
Sets the visibility of <em class="parameter"><code>mark</code></em>; the insertion point is normally
visible, i.e. you can see it as a vertical bar. Also, the text
widget uses a visible mark to indicate where a drop will occur when
dragging-and-dropping text. Most other marks are not visible.
Marks are not visible by default.</p>
