review fill/align APIs
The vte_terminal_[sg]et_[xy]_[align|fill]
API is currently on master (from #337 (closed)) and I'd like to actually release next stable with them (this is independent of #2610).
The question I have is whether the start/centre/end align enum values are ok, or if we should instead use double
s in the 0..1 range ?
@chergert any preference here from you?
