the various finders for maintainability.

John Cupitt 0b74acf7ba add a test for unpremultiply 
we actually test vipsthumbnail --linear on an RGBA image, which should

We were not detecting division by zero carefully enough, nor clipping
the alpha range sufficiently in unpremultiply.

see https://github.com/libvips/libvips/issues/1941

also see https://github.com/libvips/libvips/pull/1675 for another
difficult test case
