3c0a2e4837 fix window cycling
we were repeatedly free-ing and new-ing input mmap windows ... this made
things like zoom out on large images in nip2 much slower than they
needed to be

e9b7231ac0 add "extend" option to affine
so for upsizing with displacement (like resize) we can prevent dark
edges on bright images

libvips v8.6.0-beta: ensure interlaced PNG input works with libpng16

8a34ba6e14 Ensure interlaced PNG input works with libpng16
Manually calling png_set_interlace_handling results in the internal
num_rows member of the opaque png_structp not being correctly set.

This appears to be a limitation of libpng so probably needs fixing
upstream before the png_set_interlace_handling call can be re-added.

9c8790b40a setting EXIF data blocks sets other tags too
calling vips_image_set() to set the EXIF data block VIPS_META_EXIF_NAME
will automaticaly set other tags, like orientation etc.

406e228c9b vips_resize() is always centre convention

cb128eb258 apply --centre to upsize as well as down
we were just using the --centre flag in resize to influence downsize
behaviour -- use it to set upsize as well

5664a0d9b1 dzsave outputs extra tiles along right and bottom
the deepzoom spec wants tiles to be written along the right and bottom,
even of those tiles contain no new pixels

this patch seems to work, but needs testing
