more vips_resize() tuning
...
now we have better tuning for the anti-alias blur, we can increase the
amount we shrink by and reduce the amount we affine by
this gives a noticable speedup

try to improve vips_resize() quality
...
small improvements to vips_resize() quality:
* turn down the anti-alias filter a little so we don't smudge out texture
* don't do the final sharpening pass if we skipped the anti-alias filter
* fix a >/>= mixup which meant we didn't sharpen for small resizes

more careful p->t conversion
...
When we convert an image from "p" to "t" in vips_image_wio_input(), zap
start/gen/stop callbacks. This makes vips_region_prepare_to() read from
the "t" rather than trying to gen pixels again.
