Use the bitwise OR assignment operator to ensure that derived
classes does not overwrite the flags from the base class. Also,
move the flags from `openslideload_source` to its base class.
* 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
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.
but can't set meta correctly, try:
$ vipsheader -a sub-CC00050XX01_ses-7201_T2w.nii.gz
see all fields, but
$ vips copy sub-CC00050XX01_ses-7201_T2w.nii.gz x.v
$ vipsheader -a x.v
only see a few, odd
