MacVim Snapshot 168

Updated to Vim 8.2.2127.

*Note*: This release doesn't natively support Apple Silicon / M1 yet, but
does work under Rosetta. See below.

Features
====================

Big Sur / macOS 11
--------------------

- MacVim now has an updated app icon (#1054), and preference pane / toolbars
  have been updated to match Big Sur's interface guidelines. (#1128)
- Fixed Touch Bar warnings when launching MacVim from the terminal.
  #1114
- SF Symbol characters will show up properly as double-width as most of
  these icons would take up more than one column. Note that these
  characters are specific to macOS and would not work in other
  platforms. #1129

Renderer / scrolling performance improvements
--------------------

The Core Text renderer has been rewritten and is now much faster!
Scrolling should not stutter and lag like before and generally it should
feel a lot smoother now. Thanks to Sidney San Martín (@s4y) for the
contribution. #858

With this change, the non-Core-Text renderer is now considered
deprecated. The old renderer is accessible either through the Preference
Pane (under Advanced) or by setting the defaults "MMRenderer" to 0. It
works for now, but it will be removed in a future update as it has known
bugs.

Menu Localization
--------------------

Menus are now localized, see `:h langmenu` for how Vim menu localization
works. You can use `set langmenu=none` to turn it off if you would like. #1099

There still exists a few menu items that are not localized, and the
general MacVim GUI is not localized as well. If you would like to help,
please use #1102 to coordinate with MacVim dev team.

Getting help / Help menu
--------------------

- Help menu's search bar now searches Vim documentation as well! See
  #1095.
- Vimtutor is now bundled with MacVim, and you can access vimtutor from
  the Help menu (#1096). There is also a link to the latest release
  notes as well (#1131).

General
====================

- This release does not contain a native universal app for Apple Silicon
  / M1 Macs yet. The release binary will still work under Rosetta, which
  should provide enough performance, but if you use Python/etc plugins,
  you need to make sure you have x86 versions of Python/etc installed
  (which is still the default for Homebrew as of this release).

  MacVim is buildable under Apple Silicon, so if you need a native
  binary, you could build it yourself by downloading the source from the
  Github repository. See #1136 for progress on releasing a universal app
  for Apple Silicon.

- MacVim has enabled the Github Discussions feature, which serves as a
  good spot for general discussions and questions. See
  https://github.com/macvim-dev/macvim/discussions/1130 and check it
  out!

Fixes
====================

- Launching MacVim from the Dock with locales that use "," for decimal
  separators now works correctly. #11 (Vim 8.2.1738)
- `WinBar` menus (which are used by plugins like vimspector) now work
  properly and don't create dummy menu items. #918
- Using `:browse tabnew` no longer crashes MacVim in terminal mode.
  #1107 (Vim 8.2.1842)

Misc
====================

- Scripting languages versions:
    - Python is now built against 3.9, up from 3.8.
    - Lua is now built against 5.4, up from 5.3.

Compatibility
====================

Requires macOS 10.9 or above.

Script interfaces have compatibility with these versions:

- Lua 5.4
- Perl 5.18
- Python2 2.7
- Python3 3.9
- Ruby 2.7
