mrv2 v1.1.7

v1.1.7

• Made mrv2's custom file requester create thumbnails on demand when they are
  on view. This helps for large files like many big USD files on disk or with
  RAW files which are also slow to load.
• Fixed mrv2's custom file requester thumbnails being too high.
• Added custom RAW and several image missing formats to mrv2's custom file
  requester.
• Started cleaning up FLU's code (mrv2 custom file requester).
• mrv2's v1.1.6 was not respecting the hidden pixel bar on the Preferences
  Window, always showing it stopping.
• Fixed session files starting playback automatically even when the original
  timeline was stopped.
• Fixed a color discrepancy on YUV420 movies being too saturated.
• Rewrote the algorithm for the scaling of the window when the first image is
  loaded (or run from the command-line).
• Fixed a terrible bug on Linux X11 which would sometimes would make the X11
  server reboot on some Linux distros like Rocky Linux 8.9.
• Added OpenRV's license to mrv2 as I took inspiration for their reverse
  playback. I was doing the same on mrViewer, but I had forgotten about it.
• Update tlRender to use OTIO v0.16.0.
• Added what each contributor did so far for the mrv2 project.
  If you don't want to be listed as contributor, not list your email address,
  or something else, please let me know.
• Updated update_mrv2.py script. Tested on macOS, Windows, Rocky Linux 8.9
  and Ubuntu 22.04.4 LTS. From now on, you can rely on automatic upgrades
  if you go to Window->Preferences->Behavior->Upgrades and set them at Startup.
  When you start mrv2, it will check to see if there is an upgrade after 5 days
  of the actual release (so any portential early bugs are squashed).
• Improved translation CMake scripts.
• Added documentation on how to get Wayland working almost flawlessly on Ubuntu
  22.04.4 LTS.
• Added 120 FPS, which drops frames but it is still nice to quickly browse a
  movie.
• Darby's Rec709 coefficients and YUV shader were incorrect leading to subtle
  color shifts. Now they are fixed.
• Fixed shifting clips with annotations when transitions were present.
