<!-- Give the textview a solid-color background (the same as the pane) in
order to make the text clear when a DisplayBlock is drawn under it as
part of display_topology_pane_content.
If the padding is in the TextView, then the background will fill the
padding, which we don't want vertically, as there is a lot of vertical
padding. We do need some horizontal padding because otherwise the
rounded corners will touch the edge of the text. -->
