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.
