/**
* SECTION:matrix-event-room-redaction
* @short_description: event to designate event redactions
*
* This is the default event handler for `m.room.redaction` events.
*
* Events can be redacted by either room or server admins. Redacting an event means that all
* keys not required by the protocol are stripped off, allowing admins to remove offensive or
* illegal content that may have been attached to any event. This cannot be undone, allowing
* server owners to physically delete the offending data. There is also a concept of a
* moderator hiding a message event, which can be undone, but cannot be applied to state events.
* The event that has been redacted is specified in the `redacts` event level key.
