1f5b900f3d plumb appearance change event -> reload on macos
This commit causes a window-config-reloaded event to trigger
when the appearance (dark/light mode) is changed on macos.

It also arranges to propagate the window level config to newly
spawned panes and tabs, created both via the gui and via the
CLI/mux interface.

db6da81272 window: move away from async event queue
I added this originally thinking that it would make it easier to resolve
https://github.com/wez/wezterm/issues/695 and to integrate wgpu support,
but it's the cause of https://github.com/wez/wezterm/issues/922 so let's
take it out and more directly connect the window events to those in the
terminal.

This commit likely breaks mac and windows; pushing it so that I can
check it out and verify on those systems.

423b208780 font weight can now be specified as the underlying opentype weight
opentype allows a font to have a weight in the range 0-1000.
MacOS has its own concept of symbolic weight names and opentype
values that is a slightly different scale of boldness to Windows
and Linux.

That means that Medium could be a different range of opentype
weight values depending on the system.

To further complicate things, the font designer can name their
variant with any name they like and assign it an arbitrary
opentype weight value.

For the Operator Mono font, it has Book variant with opentype
weight 325 and a Light variant with an opentype weight of 300.

wezterm was considering these both to have `FontWeight::Light` because
that's how those values were bucketed, which results in amibiguity in
resolve the font and frustration in not being able to access one of the
variants.

This commit changes the `FontWeight` type to now hold the unambiguous
opentype weight value, and to define some symbolic aliases for
some specified weights.

When serializing, if the weight matches a symbolic alias, then that
name will be used in the canonical name (eg: as listed via ls-fonts).
Otherwise, the numeric value will be used.

When parsing the font configuration, wezterm will allow both symbolic
and numeric values.

This allows all of the Operator Mono variants to be referenced
unambiguously, although some variants have to be specified via the
numeric weight:

```
wezterm.font("Operator Mono", {weight=275, stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-XLight.otf, FontDirs
wezterm.font("Operator Mono", {weight="Light", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Light.otf, FontDirs
wezterm.font("Operator Mono", {weight=325, stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Book.otf, FontDirs
wezterm.font("Operator Mono", {weight="DemiLight", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Medium.otf, FontDirs
wezterm.font("Operator Mono", {weight="Regular", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Bold.otf, FontDirs
```

35eb7383b1 ci: simplify version number
Previously, we used `git describe --tags` to produce a version number
for non-released builds derived from the most recent tag + some info
such as the number of commits since that tag and then `g{HASH}`.

That always confuses people because the date portion at the front
looks old (it is typically the previous release) and the hash at
the end has that `g` in it.

This commit simplifies both the tag name used when making a release
and the computed version number take the date/time from the current
commit, and then append the hash.  That way the version number always
corresponds to a commit.

This scheme doesn't help detect situations where the commit is
dirty, but I don't think the old one would have helped with that
either.

fe48951e7a macos: fixup SUPER+SHIFT+[ key decoding
One of the default key assignments was registered as `SUPER+SHIFT+{`
which worked on macOS, but on Linux, would never match because the
keypress over there was (correctly) reporting as `SUPER+{`.

I originally thought that the user reported issue was a linux
normalization problem, but in looking deeper, the issue is really
that macos is doing something funky!

On macos we collect the interpreted key event as a string, and also
the interpretation of that event without any modifiers applied.

For letters this means that eg: `ALT-l` reports as `¬` for the
processed string and `l` for the unmodified string.  That's good!

However, for punctuation we get a backwards result: SUPER+SHIFT+[
produces `[` for the processed text and `{` for the unmodified
text!

This commit tries to detect this, using a heuristic that is
potentially bad on non-US layouts: if both the processed and
unmodified strings are punctuation then we bias to the unmodified
version.

With that change, that key press is correctly reported as `SUPER+{`,
and we can fix the key assignment registration to reflect that.

I quickly checked the behavior of pressing that same physical key
combination with a DEU layout active, and it appears that the unmodified
stuff is also flipped there; we get a lower-case version of something
that I think should be uppercase.  This commit doesn't change that
behavior:

```
key_event KeyEvent { key: Char('ü'), modifiers: NONE,
        raw_key: Some(Char('Ü')),
        raw_modifiers: SHIFT | SUPER,
        raw_code: Some(33),
        repeat_count: 1, key_is_down: true }

57f1aa2785 fixup build to not consider termwiz tags as wezterm tags
CI got broken by the termwiz release.  This commit teaches the
various `git describe --tags` calls to filter to the wezterm
tags which all start with the year.  We're match `20*` which should
be good for the next 79 years.

I've removed the vergen dependency as there was no way to teach it
to do the equivalent matching, and it wasn't a terrible burden
to just inline the git describe call anyway.

Adds a test and seemingly a fix for https://github.com/wez/wezterm/issues/478#issuecomment-787520977

Fira Code is OFL-1.1 licensed like the other fonts we include,
however, I'm not distributing Fira Code with wezterm.

0597684ebd Render custom block glyphs
As explained in the docs included in this commit, ideally this
wouldn't be needed, but due to a long-standing hinting bug in
freetype <https://gitlab.freedesktop.org/freetype/freetype/-/issues/761>
it seems most expedient to just render our own block glyphs,
so that's what this does!

db08b8c1dc add window:set_config_overrides lua method
This commit expands on the prior commits to introduce the concept
of per-window configuration overrides.

Each TermWindow maintains json compatible object value holding
a map of config key -> config value overrides.

When the window notices that the config has changed, the config
file is loaded, the CLI overrides (if any) are applied, and then
finally the per-window overrides, before attempting to coerce
the resultant lua value into a Config object.

This mechanism has some important constraints:

* Only data can be assigned to the overrides.  Closures or special
  lua userdata object handles are not permitted.  This is because
  the lifetime of those objects is tied to the lua context in which
  they were parsed, which doesn't really exist in the context of
  the window.
* Only simple keys are supported for the per-window overrides.
  That means that trying to override a very specific field of
  a deeply structured value (eg: something like `font_rules[1].italic = false`
  isn't able to be expressed in this scheme.  Instead, you would
  need to assign the entire `font_rules` key.  I don't anticipate
  this being a common desire at this time; if more advance manipulations
  are required, then I have some thoughts on an event where arbitrary
  lua modifications can be applied.

The implementation details are fairly straight-forward, but in testing
the two examplary use cases I noticed that some hangovers from
supporting overrides for a couple of font related options meant that the
window-specific config wasn't being honored.  I've removed the code that
handled those overrides in favor of the newer more general CLI option
override support, and threaded the config through to the font code.

2d02df5f38 add --config name=value CLI options
`wezterm`, `wezterm-gui` and `wezterm-mux-server` now all support
a new `--config name=value` CLI option that can be specified
multiple times to supply config overrides.

Since there isn't a simple, direct way to update arbitrary fields
of a struct in Rust (there's no runtime reflection), we do this
work in lua.

The config file returns a config table. Before that is mapped
to the Rust Config type, we have a new phase that takes each
of the `--config` values and applies it to the config table.

For example, you can think of configuration as working like this
if wezterm is started as `wezterm --config foo="bar"`:

```lua
config = load_config_file();
config.foo = "bar";
return config;
```

The `--config name=value` option is split into `name` and `value`
parts.  The name part is literally concatenated with `config` in
the generated lua code, so the name MUST be valid in that context.
The `value` portion is literally inserted verbatim as the rvalue in the
assignment.  Not quoting or other processing is done, which means
that you can (and must!) use the same form that you would use in
the config file for the RHS.  Strings must be quoted.  This allows
you to use more complicated expressions on the right hand side,
such as:

```
wezterm --config 'font=wezterm.font("Fira Code")'
```

The overrides stick for the lifetime of the process; even if
you change the config file and reload, then the value specified
by the override will take precedence.

dd70a8a53b introduce freetype_load_flags and freetype_load_target config
In the earlier times wezterm supported different font rasterizers,
and the configuration was a bit vague and generic to accomodate
differences in how the rasterizers worked.

Since then, we've standardized on freetype.

One of the things that's been bothering me for a while is that
we have some fiddly logic to transform from the config to the freetype
flags.

This commit does away with the transformation and simply exposes
the two sets of freetype options.

The main thing that I expect people to play with is
`freetype_load_target` which can have one of the following values:

```
pub enum FreeTypeLoadTarget {
    /// This corresponds to the default hinting algorithm, optimized
    for standard gray-level rendering.
    Normal,
    /// A lighter hinting algorithm for non-monochrome modes. Many
    generated glyphs are more fuzzy but better resemble its original
    shape. A bit like rendering on Mac OS X.  This target implies
    FT_LOAD_FORCE_AUTOHINT.
    Light,
    /// Strong hinting algorithm that should only be used for
    monochrome output. The result is probably unpleasant if the glyph
    is rendered in non-monochrome modes.
    Mono,
    /// A variant of Normal optimized for horizontally decimated LCD displays.
    HorizontalLcd,
    /// A variant of Normal optimized for vertically decimated LCD displays.
    VerticalLcd,
}
```

I expect most people will want to set this to one of `Normal`, `Light`
or `HorizontalLcd`.  `HorizontalLcd` is what `font_antialias=Subpixel`
used to select.

08b6043166 gui: introduce foreground_text_hsb transform
This allows explicitly manipulating the hue, saturation, brightness
of the text rendered in the terminal, allowing users to dial in
the accidental effect that was introduced by
d886de8300

For example, this will punch up the brightness:

```
  foreground_text_hsb = {
    hue = 1.0,
    saturation = 1.0,
    brightness = 1.5,
  },
```
