According to
https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Multithreading/CreatingThreads/CreatingThreads.html#//apple_ref/doc/uid/20000738-125024
Cocoa is by default not multithread-safe for programs that use the posix
api for creating threads:
"
For multithreaded applications, Cocoa frameworks use locks and other
forms of internal synchronization to ensure they behave correctly. To
prevent these locks from degrading performance in the single-threaded
case, however, Cocoa does not create them until the application spawns
its first new thread using the NSThread class. If you spawn threads
using only POSIX thread routines, Cocoa does not receive the
notifications it needs to know that your application is now
multithreaded. When that happens, operations involving the Cocoa
frameworks may destabilize or crash your application.
"
That includes Go programs.
The fix, as discovered by Steeve Morin, is to create and launch
an empty NSThread.
Add a package that does that, and use it everywhere Cocoa is used.
Sigh.

Allows things like "ctrl-{" and ".".
All punctuation is returned as-is, e.g. "!" is "!", not "shift-1", and
"{" is "{", not "shift-[".
Also add the Enter key as a known key (fn-return on my Mac).

Function keys don't have a natural rune representation so switch
Event.Name to be a string to fit "F1"-"F12".

Before this change, Gio tries hard to come up with a reasonable UI scale
factor on desktop OSes derived from the physical dimensions and
resolution of connected monitors. Gio also attempts to detect the user
specified system UI scale and apply it.
However, all that is complex and misguided:
- The UI scale should not depend on whatever monitor is connected at
program startup - For multiple monitors, it's unclear which one to base
the scale off. - Applying both a monitor derived scale *and* the user
specified scale is wrong, because the user scale is relative to some
fixed scale, not Gio's derived scale. - With an automatic scale, Gio
does not respect user preference and will not have a similar scale to
other programs on the desktop.
Get rid of the the automatic UI scale detection and rely only on the
user scale.
