...
* nsgifload: avoid minimise after mapping
Not reliable on Windows.
* nsgifload: prefer use of `VIPS_FREEF` macro
* Improve `test_descriptors.c`
* Only build `test_descriptors` when targeting Linux

Cleanup gettext handling ( #2695 )
...
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.

disable webp shrink-on-load if it will judder
...
Webp decode can only shrink-on-load to int boundaries. This means that frames
in an animation which only update part of the canvas can get displaced by
up to 0.5 pixels, causing juddering.

d1094847a3
remove no-alpha webp support
...
We used to try to spot webp images with no alpha and load them as plain
RGB, but it turns out this is difficult to do reliably, especially
for animated images.
This patch simply removes support, so all webp images now load as RGBA.

more consistent behaviour for multi-page load
