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

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

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.
