The broot icon font has glyphs with horizontal advance set to 0. That
would cause us to consider the glyph to be zero width, so handle that as
a special case. Note that it is legit for certain cells to end up with
a zero advance/width during shaping if they represent combining
characters: this is more common in Arabic scripts.

The condition should be: dpi-changed && (close-enough-stuff)
but was (dpi-changed && (some-close-enough-stuff)) ||
(other-close-enough-stuff).
The net result was toggling non-native full screen on macos could
falsely try to do scale change handling even though the dpi was
unchanged, because the window resized by only a couple of pixels.
Pretty much the same test plan as b4c4c85683
but start wezterm:
./target/debug/wezterm -n --config 'ssh_domains={{name="s",remote_address="localhost"}}' connect s
This reliably propagates focus=true events, but if the client switches
focus away from a mux pane to a local pane, then the focus=false event
may not be propagated to the remote mux.

We don't assume that we start up focused, and some WM don't tell
us our focus state, so prior to painting, if we don't know the
focus state, explicitly query it and synthesize a focus change event.

Flesh out the get_os_parameters impl for macOS. When running on a
system that provides `NSScreen::safeAreaInsets`, use that to determine
the border required to avoid the "notch" on certain models of mac.
In the GUI layer: when the os parameters include a border, adjust
the render position to account for it.
This is a bit of a speculative change, as I don't have a mac with
a notch.

This commit allows specifying a scaling factor as part of the font
attribute definition. This scaling factor is fed through to the
rasterizer and the shaper to adjust the actual font size that is
loaded.
The intent is to provide manual control for situations where the
fallback font has a different scale to the primary font and renders
either too small or too large.
The concrete example is
https://github.com/wez/wezterm/issues/1761#issuecomment-1079708207 where
the CJK fallback looks too small.
The scaling factor doesn't influence font metrics so it may also be
desirable to configure line height.
```lua
local wezterm = require 'wezterm'
return {
line_height = 1.2,
font = wezterm.font_with_fallback({
"JetBrains Mono",
{family="Microsoft YaHei", scale=1.5},
}),
}
```
freetype can't handle a wide range of encodings for
font names and can return strings like `?????` when
the family name is only present in the font as a non-unicode encoding,
such as Chinese.
This commit improves our handling of the font name table
and prefers to use results from processing that over the
results returned for eg: font family directly from the
freetype API.

The metadata is useful from a troubleshooting/diagnostic perspective.
`.cast` isn't on github's list of allowed file name suffixes, so make
it a simple text file for convenience.
These are intended to replace the `wt-record` and `wt-replay` scripts
that are primarily for me to diagnose wezterm issues.
The thinking is that this gives a cross platform implementation of
this functionality and squashes out some of the pain of dealing with
different versions and file formats.
The new subcommands use the asciicast v2 file format, meaning that
wezterm can record for asciicast/asciinema and vice-versa.
This commit only handles unix; windows support will follow in
a separate commit.
