John Cupitt 828b36dfe5 fix --fail option to jpegload
getting --fail on jpegload working means tilecache must terminate on tile
calc error

make openslideload not report tile calc errors, it might need a --fail
option too

John Cupitt 65105a9442 upsize with something other than nearest
vips_resize() uses to just use nearest when upsizing, following standard
practice in repro. This is often unfortunate for image processing, where
small nearest upsizes will produce obvious aliasing.

It now picks a VipsInterpolate which corresponds (roughly) to the
selected VipsKernel and uses that with affine for any upsizing.

John Cupitt f3326c8126 better vips_resize() for cubic/linear/nearest
vips_resize() used to do most of a downsize with vips_shrink() and the
final 200 - 300% with vips_reduce(). This was correct for lanczos2/3,
but not right for linear/cubic, which need more shrink and less
reduce to avoid aliasing.

This patch makes vips_resize() leave the final 100 - 200% to
vips_reduce() for linear/cubic, and leave everything to reduce for
nearest.
