require clipping for dithering sample conversion functions?

Issue created by @RossBencina

Consider whether functions which dither but don't clip should exist, V18 automatically enabled clipping whenever dithering was selected. Perhaps we should do the same.

This would have the advantage that it would eliminate many of the unimplemented converters in ticket #35

If we dither then that could cause valid in-range data passed by the app to go out-of-range.
So, yes, I think if we dither then we should always clip.
