Will not occur in serializations of GEGL graphs, but can occur in
manually provided data like when using GIMPs GEGL graph operation,
as reported in issue #308.

Always clip the cluster size value to the maximum input buffer dimension.

This just do a build on latest Fedora, .gitlab-ci.yml-ignored contains
much more that could be backported later. This is better than nothing.

It uses freedesktop ci-templates for managing docker images:

Commit be8978ba demoted libgegl-npd to a private library, not caring
about the fact that this library is actually needed externally. Its API
is meant to be exposed publically, headers are installed and so on. In
particular, it is used by GIMP so this commit actually broke GIMP
builds, as well as our CI.

I can understand that adding this side library this way is not so
conceptually ideal, so one should be welcome to provide alternatives,
such as maybe its own pkg-config file, and also changing the API
namespace to gegl_npd_*() or something like this. But until this is done
and GIMP code and build at least is ported to such updated API, we
should not hide away this library meant to be public.

This is a workaround while waiting for !123 to be merged when we'll
depend on Meson 0.57.0.

This makes Meson fallback to subproject if some dependencies are not
found on system.

This fix usage of gegl as subproject.

This to easier permit building GIMP-2.10 on some older distros.

We now have to say which pixel format to decode to.
This sets it up to match the `babl_format ("R'G'B'A u8")`.

LibNSGIF now supports decoding to multiple different pixel
buffer formats. It has also had slight improvements to the
handling of malformed GIFs.

This denoising operation decomposes the input buffer to sliding overlapping
patches, calculates the DCT denoising in each patch, and then aggregates the
denoised patches to the output buffer averaging the overlapped pixels.
