<p>An interface channels can implement to support a picture. Most

Text channels, and can also be used on Call channels.</p>
<tp:rationale>
This is a separate interface from
<tp:dbus-ref namespace="ofdT.Channel.Interface">RoomConfig1</tp:dbus-ref>
because (a) it's possible some protocol might support pictures for
1:1 chats; and (b) it avoids downloading an unwanted picture in a
GetAll request.
