22075	Add glycin and let gdk-pixbuf use it	Xi Ruoyao	blfs-book	"The release note of new gdk-pixbuf recommends to use glycin (https://download.gnome.org/sources/glycin/2.0/) on Linux, and non-glycin loaders will be removed (moving into a separate repo that nobody will maintain) in the future.

The problematic part about glycin is for AVIF it only supports libheif, not libavif that we already have.  And libheif needs libde265 in turn (because it supports both HEIF that uses a x265 decoder, i.e. libde265 and AVIF that uses an AV1 decoder, i.e. libaom or libdav1d).

So one approach for the book is:

{{{
+ libde265
+ libheif
+ glycin
- webp-pixbuf-loader (can be completely superseded by the glycin loader)
}}}

libde265 and libheif can also be used by gimp, gst-plugins-bad, and imagemagick.  We cannot remove libavif as many packages only support it, not libheif.

Another approach is not to add libheif, but leaving AVIF to be loaded by the current loader in the book (the one bundled in libavif), we'd have:

{{{
+ glycin
- webp-pixbuf-loader
