This method is automatically invoked in response to an
edited(_: message or an
end message if edits were made within the scope of a
begin block. You should never need to invoke it directly.
This method begins by posting an
will to the default notification center (which results in the delegate receiving a
text message). Then it fixes attributes. After this, it posts an
did to the default notification center (which results in the delegate receiving a
text message). Finally, it sends a
text message to each of the receiver’s layout managers using the argument values provided.
