+- Switch from LCMS to SKCMS: libjxl core can use either, but
+  plugins can only use SKCMS. Exercising two CMS simultaneously
+  also is silly. Delete 0001-Remove-LCMS-mutex.patch .

+- Build plugins:
+  * Add _service file to generate skcms tarball (needed to build
+    plugins).
+  * Add skcms tarball as source and copy extracted dir to
+    ./third_party/ so cmake can find it.
+  * Split out new packages:
+  * gdk-pixbuf-loader-jxl: Pixbuf loader for supported apps.
+  * gimp-plugin-jxl: Plugin to allow gimp to work with JPEG XL
+    files.
+  * jxl-thumbnailer: Thumbnailer and mime files to allow
+    generating thumbnails for JPEG XL files.
