Robert Jordens e870b27830 wavesynth: new semantics, fix compensation
* "trigger" now means that the corresponding line will only start
  once the trigger line is high.
* "jump" is implicit as the last line in a frame must jump back.
* spline coefficients are now compensated for finite time step size
