* start adding dzsave to a target
made a thing for gsf to write to a target
* fix stray tabs in dzsave
* fix dzsave write to "."
Early versions of libgsf did not support writing to ".", so we had an ugly
workaround, but this should now be OK.
Fixing this ought to make write to target simple
* dzsave_target compiles
no idea if it works though
* seems to work now
creates stray 0 length files though, very odd
* fix stray files from dzsave
next: save to buffer is returning null
* fix buffer flush in dzsave
all tests pass!
* update changelog
* compiles, but untested
* works, but libtiff needs seek for write
next: add seek methods to target
* add target seek and read
seem to work
next: disc temps for disc output
* add libnsgif COPYING
oops, we were missing the COPYING file
see https://github.com/libvips/libvips/issues/2800
thanks mika-fischer
* tiffsave uses a disc temp if it can
* revise temp target rules
only make a disc temp if we are writing to a filesystem target
* add new target methods to targetcustom
since finish did not return an error code
also make sure we don't call target_end from inside _dispose, since that
can't signal error either
see https://github.com/libvips/libvips/issues/2801
* quick proposal
warn on startup if untrusted operations might run
use vips_block_untrusted_set() to block untrusted operations, set an env
var or make a file to stop the warning
* mark fits, nifti and svg as untrusted
* remove the annoying "untrusted" warning message
better to warn on the download page
leave vips_block_untrusted_set() since it's obviously useful
* separate UNTRUSTED and BLOCKED
* typos
* add VIPS_BLOCK_UNTRUSTED env var
* move BLOCK_UNTRUSTED after plugin load
obviously, ooops
* add a test, disable *magick
although *magick is fuzzed, it's probably safer to disable it in
untrusted environments
* mark some more operations as untrusted
* quick hack
won't even compile
* works!
at a basic level, anyway
* start wiring up metadata
* metadata done
* add spng interlaced save
* start adding index support
* fix palette save

thanks klies
he commit message for your changes. Lines starting
* look for spng.pc and libspng.pc
It can be called either, frustratingly.
* fix PACKAGES_USED for spng .pc changes
