- Improve integral sauvola by rounding threshold correctly
- The Sauvola functions can now process any image.Image, not
  just an image.Gray
- Add ImageWindower interface and use it to generalise
  wipesides.go
- Rely on Bounds() for image bounds rather than implementation-
  specific stuff in integralimg

Note that a couple of the wipesides tests are now failing. It's
possible that this is due to fixed or introduced bugs (let's hope
the former) changing sensible thresholds. Will need to look into
this and sort it.
