the interpolation from last to first value makes sense if you want to  
use the wavetable as a lookup for an oscillator, i.e. if you want to  
loop that thing.
in the waveshaping context, i can't see any reason why this would be  
desirable.

i don't know what's really going on, but i only get correct results  
for odd table sizes.
