- Remove unused libgif-dev dependency from CI.
- Remove no longer relevant comment from testsuite.
- Use yes/no instead of boolean values in configure.ac.
switch GIF save to frame at a time
And make a new colormap if the frame average changes. This keeps memory use low, even for very large GIFs, though is somewhat slower.

only include source files in make dist for libnsgif and module/
we were just including the whole directory, which stopped the derived
files (eg. the .la archives) from being rebuilt on other platforms
By default, a dynamically loadable module is built for *magick (i.e.
`--with-magick=module`) when:
* ImageMagick or GraphicsMagick is found;
* GModule is supported (`gmodule_supported` pkg-config variable).
This can be overridden on the command line with:
* `--without-magick` - to disable *magick usage;
* `--with-magick[=yes]` - to restore the previous behavior;
* `--disable-modules` - to disable the build of dynamic modules.
By default, a dynamically loadable module is built for poppler (i.e.
`--with-poppler=module`) when:
* poppler is found;
* GModule is supported (`gmodule_supported` pkg-config variable).
This can be overridden on the command line with:
* `--without-poppler` - to disable poppler usage;
* `--with-poppler[=yes]` - to restore the previous behavior;
* `--disable-modules` - to disable the build of dynamic modules.
By default, a dynamically loadable module is built for libheif (i.e.
`--with-heif=module`) when:
* libheif is found;
* GModule is supported (`gmodule_supported` pkg-config variable).
This can be overridden on the command line with:
* `--without-heif` - to disable libheif usage;
* `--with-heif[=yes]` - to restore the previous behavior;
* `--disable-modules` - to disable the build of dynamic modules.
By default, a dynamically loadable module is built for OpenSlide (i.e.
`--with-openslide=module`) when:
* OpenSlide is found;
* GModule is supported (`gmodule_supported` pkg-config variable).
This can be overridden on the command line with:
