- Textview: Wrap text, set padding
- ListMultiTreeView: Align checkboxes to the right
- Add a adjustment element that sets default sizes on the columns
- Allow two new options 'form-width' and 'left-width' to customize sizes
Remove checking for font_scale, Gtk.TextIter.get_attributes() seems buggy at
the moment, and we dont need to check the current scale to apply a new scale
Fixes#9067
