Another issue about the text boxes:
If we use some gtk-feature to do the wrapping of the text for us, then
there's the danger that when one rescale things, due to some roundings
happening differently suddendly the wrapping changes. Similarly,
wrapping could change when exporting to pdf... or maybe even when
opening the document on a different computer?
As a solution to this, I'd propose that in the moment the user finishes
editing, the wrapping points are saved, and as long as the user doesn't
re-edit the text, it is drawn with those wrapping points. In particular,
we only need the edit-text widget to handle wrapping, whereas for
showing text while it's not edited, I would just use the same widget as
before, with "\n"s temporarily inserted at the wrapping points.
Best,
Immi
