So perhaps the insert-text signal should be emitted after the heights have been measured? Or there should be a an additional signal emitted after that has happened.
Meanwhile I have found that I cannot use the TextViewer widget because of the very slow repainting and flickering that takes place as a result of ...set_text() and the callbacks needed to keep the vertical adjustment in place.
I'm considering writing a ScrolledLabel widget instead that effectively would work as a viewport to a list of PangoLayoutLines. But I think it is a shame that the TextViewer cannot be used for this.

scroll to it. However, in your insert_text() callback it is too early
to do this (the text has not been measured yet probably).
