a different idea:  keep your current C code and write a 'coroutine
caller' in Lua.

a user could write something like this:

app.add_code (function (api)
   api.move_to (start position)
   local face = 'happy'
   api.draw (face)
   api.wait (60)
   local face = 'wink'
   api.draw (face)
   api.dissolve_to_black()
end)


where add_code creates a coroutine with the given function, and calls
it with an 'api' object that encapsulates a reference to the
coroutine, and methods that manage the spaghetinnes with callbacks
that know the coroutine to resume.
