To add another denoise bug: setting denoise at any nonzero value and
then setting the preview at 5% segfaults here. It is probably due to
this incorrect assumption in ufraw_ufraw.c:ufraw_convert_image_area()
in the denoise section:
int border = 16 * 2 / uf->ConvertShrink;
the border distance is actually the 1<<lev argument passed to the
hat transform in the wavelet denoise function and always reaches 1<<4
(i.e. 16) independent of the ConvertShrink value.
