* 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

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
