fe7bd9bdcc add vips_resize() 
a wrapper over affine that just scales ... much faster from the
command-line, since it can set SEQ mode

ce428ffa94 more vipsthumbnail fixes 
- handle CMYK images
- use unbuffered mode, we have a cache already
- don't try to anti-alias on upscale

ed3c56fcbf add an anti-alias filter to vipsthumbnail 
vipsthumbnail blurs slightly between shrink and affine, if the affine
will be doing a large shrink

ebec31fe4a 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.

004c98f296 pngsave interlaced makes a copy of the image 
interlaced png is hard to write: you have to make seven passes over the
image to make the whole file. It advertises itself as sequential, it
needs to only ake a single pass. Therefore, it must take a copy in
memory of the image to write.

0114afa5fb limit nthr on tiny images 
we always made N threads for a threadpool ... we could end up making
loads of threads we never used if the image was tiny

for very small images, limit the number of threads we make
