Numa 0.28.0

Numa 0.28.0, a raw developer for Linux.

• Numa-0.28.0-x86_64.flatpak:
  flatpak install --user Numa-0.28.0-x86_64.flatpak. It needs Flatpak with
  Flathub added, because the GNOME 50 runtime is fetched from there the first
  time. It installs over any earlier version; close Numa first.

New

• A calmer editor. One bar at the top: crumbs, Undo, Redo, Before, Export
  and the menu. The row of controls under it is gone; the photograph's sections
  are at the top of the menu, each with its key.
• Looks. Presets became Looks: the camera profile on top, then Presets and
  LUTs. The picker's tooltip says where the profile comes from, and now follows
  a profile picked by hand.
• Automatic uses Numa's own profile where there is one (X-T5, X-T4, X-S10,
  EOS R5, D850, A7R III). Preferences › General › Colour › Camera profile
  chooses what Automatic means: Numa's own, RawTherapee or Adobe, or the
  camera matrix. Photographs on Automatic from those cameras look different;
  pick "RawTherapee or Adobe" to keep the old colour. Edited thumbnails are
  rendered once more.
• A profile is only used on the camera it was made for: one pasted onto
  another body falls back to Automatic.
• Histogram, Waveform or Parade from a right click on the graph.
• JPEG and HEIF files show their EXIF on the info page, and a photograph with
  no camera data says so once instead of showing empty groups.
