This is for a gui who needs to know the frame of a beat if a proposed tempo section were to be placed there.
You probably shouldn't use this unless you know what you're doing,
as it doesn't recompute the tempo map and will make a ramp invalid intil that next happens.
It is assumed that the next frame calculation is the last time you need this c_func before the next do_insert() and/or recompute_map().
