Comment (by kyngchaos):

 OK, something like this?  Ignoring the wraparound for now, new set of
 patches and new source for fallback interp functions.

 I made all interp functions return a status value:

  * 0 on successfull non-null interpolation OR if the nearest input cell is
 null -> no further interpolation required
  * 1 if the interpolated output is null -> fallback to the next
 interpolation level

 I don't know about inlining, so feel free to suggest how to do that, if
 you think it will speed it up significantly.
