Well, if you have a TTF, there's nothing else. Any high-level
operation is inevitably bound to its design tool; it's simply not
possible to have *any* reliable mapping: Coordinates might change,
glyphs might be scaled, the whole font's EM value might change, etc.,
etc.
A tool that suddenly changes point coordinates between releases is,
well, not reliable IMHO.
Just assume that you are doing manual hints! Hinting with ttfautohint
is essentiall the same: It's the very last step before shipping.
