1.1.6 - A Lot of fixes and stuff

RAVU-Zoom, SGSR, X11 fixes, COSMIC/Niri fixes, Crash handler and more!

Upscaling:

The FSR filter is gone, replaced by two that look better and let you choose the
trade.

• RAVU-Zoom (anti-ringing) is the new default. It looks each neighbourhood up
  in a table trained offline instead of guessing from a formula, and clamps the
  result to the range that neighbourhood already spans, so it cannot trace a
  bright border around a hard edge
• SGSR1 (edge direction) weights its samples along the edge it finds, and is
  much the cheaper of the two. Worth picking on an integrated GPU
• Both run at full sharpness, so the sharpness slider is gone. It existed to
  recover detail these two do not lose

When something goes wrong:

• Stud now tells you when it has crashed, and offers the log for that session.
  Anything that ends a session without being asked to counts, including being
  killed outright
• Logging no longer makes the engine wait on a disk. Each process hands its lines
  to Stud's launcher, which writes them in batches, and writes immediately the
  moment something goes wrong

Windows, input and accounts:

• Fixed a window that came up with a black border around the picture, took no
  input, and only came right when you resized it by hand (COSMIC)
• Fixed the issue on niri where the window would constantly blink until it's resized.
• A dragged window moves as you drag it rather than lagging behind
• The frame caps work again, so Stud no longer draws at full rate for a window
  nobody is looking at
• Holding a key on X11 keeps it held, instead of the server repeating it as a
  press and a release
• The GPU picked in Settings is the one Stud uses. It was being offered to the
  engine first rather than alone, so a machine with two cards could still end up
  on the other one
• Signing out forgets that account's saved session, and only that account's. A
  logout from inside the engine forgets the stored credential too
• Closing the window leaves the experience before it leaves the server, so you
  are not left standing in the game you just closed

Underneath:

• A lost GPU device no longer takes the session with it: what the engine left
  behind is freed, and a device is kept until the replacement has proved itself
• The engine's own leaked buffers and allocations are released with the device
  that owned them
• Fixed the emulated PVRTC extension not being counted, so the engine can find it

Known bugs:

• On NVIDIA, a 12 seconds freeze may or may not happen, randomly, a single time. This bug is already investigated (unfixable from stud's side), documented and will be soon reported to NVIDIA.
• X11 may show a black screen for a few milisseconds when the minimized window is brought to foreground
• Sometimes, clicking to join a game on Roblox launcher, stud may or may not hang on home screen for a few seconds.

Warning

Stud is still a work in progress: it boots, logs in, renders the real app and joins real games, and it also breaks in ways nobody has measured yet. A log from a machine that isn't ours is the most useful thing you can send (the tray's Export logs puts a session in one file)
