restore bandfmt after unpremultiply in thumbnail
...
vips_unpremultiply() always outputs float. If you save the output of
vipsthumbnail to a format that supports float files, like tiff, it won't
ever get cast back to the source format.
Example:
$ vipsheader Opera-icon-high-res.png
Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload
$ vipsthumbnail Opera-icon-high-res.png -o x.tif
$ vipsheader x.tif
x.tif: 117x128 float, 4 bands, scrgb, tiffload
This change makes it note and restore BandFmt aropund pre/unpremultiply.

now we have better tuning for the anti-alias blur, we can increase the

this gives a noticable speedup

small improvements to vips_resize() quality:

* fix a >/>= mixup which meant we didn't sharpen for small resizes
