24c07cfde2 revert an accidental ABI break 
the new window manager code in 8.6.1 changed the prototype of an internal
function which was visible in the public API

this patch renames the function, adds it to an internal header instead,
and adds a stub for the old prototype

9febc3ac3e seq could be set on small random images 
images under the disc threshold opened in random access mode from
sequential loaders would have the seq tag set on them, causing
performance problems with vips_resize()

eea8b61f3f tiny cleanup 
make the code for error during jpeg buffer write a little cleaner --
rather than calling the jpeg term method ourselves, have a separate
destroy function for the write buffer

See https://reproducible-builds.org/ for why this is good.

Merge pull request #821 from lovell/png-start-read 
libvips v8.6.0-beta: ensure interlaced PNG input works with libpng16
 2017-12-05 08:26:29 +00:00
Lovell Fuller
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.
