Looks like a bug in Py_BuildValue for s# values on that platform. Workaround by
constructing the string directly and passing to to Py_BuildValue.

Catalina is actually already EOL as of July 2022 but we dont need
anything from newer releases that isn't detected at runtime. Going to
Catalina allows us to use a better format for the generated DMG (UMNO
instead of ULFO which compresses better).
For some reason destroying the shadow surfaces causes mutter to render one of them at its old relative position. So workaround by not destroying the surfaces, modern mutter anyway seems to hide them when the window is docked.

Prevents users from having to install their own NERD font. System fonts
are still used preferentially on Linux but on macOS the builtin one is
used preferentially. Cant find any CoreText API to change this.
Still has to be implemented on macOS. And need to add code to the build
system to bundle the font when building.
The problem was caused by CoreText falling back to the glyph for the
ASCII hyphen U+00AD when the font does not contain a glyph for U+2010.
However, HarfBuzz does not do this automatic fallback (see
https://github.com/harfbuzz/harfbuzz/issues/517). This leads to the
character not being rendered.
To fix this we specialize HarfBuzz glyph lookup for this character
to follow CoreText. HarfBuzz should really do this automatically when
the hb_font is based on a CTFontRef, but I dont have the time/energy to
argue with its maintainers. Note that HarfBuzz already does this
automatic fallback for U+2011.
Hopefully, there aren't many more such special cases in CoreText.

labwc is unique among Wayland compositors in implementing fractional
scale but not preferred integer buffer scale events. We didn't cater to
this particular combination of before. And to top it off it appears to
have no way for the user to set/control the scale so I cant even test
what it will do with fractional scales other than 1. Sigh. As with all
things Wayland, you need to be a masochist to subject yourself to them.
Fixes#7540
