 *   <link linkend="conversations-conversation-created"><literal>"conversation-created"</literal></link>
 *                       signal is emitted).
 * @destroy_conversation: Called just before @conv is freed.
 * @write_chat: Write a message to a chat. If this field is %NULL, libpurple
 *              will fall back to using @write_conv.
 *              See purple_conversation_write_message().
 * @write_im: Write a message to an IM conversation. If this field is %NULL,
 *            libpurple will fall back to using @write_conv.
 *            See purple_conversation_write_message().
 * @write_conv: Write a message to a conversation. This is used rather than the
 *              chat- or im-specific ops for errors, system messages (such as "x
 *              is now know as y"), and as the fallback if @write_im and
 *              @write_chat are not implemented. It should be implemented, or
 *              the UI will miss conversation error messages and your users will
 *              hate you. See purple_conversation_write_message().
 * @chat_add_users: Add @cbuddies to a chat.
 *                  <sbr/>@cbuddies:     A GList of #PurpleChatUser structs.
 *                  <sbr/>@new_arrivals: Whether join notices should be shown.
 *                                       (Join notices are actually written to
 *                                       the conversation by
 *                                       purple_chat_conversation_add_users())
 * @chat_rename_user: Rename the user in this chat named @old_name to @new_name.
 *                    (The rename message is written to the conversation by
 *                    libpurple.) See purple_chat_conversation_rename_user().
 *                    <sbr/>@new_alias: @new_name's new alias, if they have one.
 * @chat_remove_users: Remove @users from a chat @chat.
 *                     See purple_chat_conversation_remove_users().
 * @chat_update_user: Called when a user's flags are changed.
 *                    See purple_chat_user_set_flags().
 * @present: Present this conversation to the user; for example, by displaying
 *           the IM dialog.
 * @has_focus: If this UI has a concept of focus (as in a windowing system) and
 *             this conversation has the focus, return %TRUE; otherwise, return
 *             %FALSE.
 * @send_confirm: Prompt the user for confirmation to send @message. This
 *                function should arrange for the message to be sent if the user
 *                accepts. If this field is %NULL, libpurple will fall back to
 *                using purple_request_action().
 *
 * libpurple needs to tell the user interface when certain things happen in a
 * conversation and it uses this structure to do so.
 *
 * Any UI representing a conversation must assign a filled-out
 * #PurpleConversationUiOps structure to the #PurpleConversation.
