If a font doesn't have any latin glyphs then we'd compute 0 as the
average width. Later, during rendering, we'd compute an `inf` scaling
factor and then subsequently fail to allocate texture space.
This commit takes the average width from a "random" selection of glyphs
(whatever the first few glyphs in the font may be) to avoid that
situation.

I didn't recreate precisely the situation in the issue, but I
tried pressing both `AltGr 8` and `CTRL ALT 8` with a DEU
layout active and both now result in `[` being emitted.

80214319ae broke the use of RUST_LOG to
turn up trace logging.
This commit refactors logger initialization into the env-bootstrap crate
so that it is centralized, and adopts the use of `WEZTERM_LOG` to
override the default logging filters, rather than `RUST_LOG`.
The default is 1.0. `line_height` is used to scale the effective
cell height, increasing the amount of space between font baselines.

in ab342d9c46 I started to rearrange how
the output processing thread works. It wasn't quite right, so this
commit tidies things up.
The main change here is that there is now back-pressure from the output
parser on the reader; if it is taking a while to parse the output then
we don't buffer up so much input.
This makes operations like `find /` followed immediately by `CTRL-C`
more responsive.
With this change, I don't feel that the
`ratelimit_output_bytes_per_second` option is needed any more, so it
has been removed.
Teach the core text locator how to obtain the system fallback list
and add that to the fallback.
Fixup handling of ttc files on macOS; we'd always assume index 0
when extracting font info from the font descriptor. We now make
the effort to enumerate the contents of the TTC and find a match.
https://wiki.lazarus.freepascal.org/Cocoa_DPI states that the dpi
on macOS is 72. That matches up to the experimental results reported
in #332 (in which 74.0 appears about the right size).
This commit introduces a `DEFAULT_DPI` constant that is set to 72 on
macOS and 96 on other operating systems.
The result of this is that a 10 point Menlo font now appears to be
the same size in Terminal.app and WezTerm.app.

This commit improves input processing on macOS; passing the keyUp
events to the input context is required for dead keys to correct
process their state transitions.
In addition, we weren't passing key events through if any modifiers
were down; for dead keys we need to allow Option through.
This commit rigs up a little bit of extra state to avoid double-emitting
key outputs from the input context.
Lastly, the virtual key code is passed through to the KeyEvent to
enable binding to raw keys per 61c52af491

Adds an option to control how wide glyphs (more specifically: square
aspect glyphs) are scaled to conform to their specified width.
The three options are `Never`, `Always`, and `WhenFollowedBySpace`.
When a glyph is loaded, if it is approximately square, this option is
consulted. If overflow is permitted then the glyph will be scaled
to fit only the height of the cell, rather than ensuring that it fits
in both the height and width of the cell.

This makes it possible to configure wezterm to eg: triple click
on command input (or output) to select the entire input or output
without messing around trying to find the bounds.
The docs have an example of how to configure this; it requires
setting up shell integration to define the appropriate semantic
zones.
There were two problems:
* It was using an old code path that didn't even try to resolve the cwd
* The NewWindow code path would "forget" the originating window and then
fail to resolve the current pane + path from the new, empty window
that it is building.

Adds some supporting methods for computing the `SemanticZone`s
in the display and a key assignment that allows scrolling the
viewport to jump to the next/prev Prompt zone.
This avoids having a green (by default) border around the cursor.
The dynamic color escape sequences have been updated to also
change the border color when the cursor background color is changed.
This commit revises the opacity configuration to make it more
consistently applied.
* `window_background_opacity` controls the overall window capacity,
whether a background image is present or not.
* When a background image is present, or if the window is transparent,
then text whose background color is the default background is
changed to have a fully transparent background.
* `text_background_opacity` controls the alpha channel value for
text whose background color is NOT the default background.
It defaults to 1.0 (fully opaque), but can be set to be
transparent by setting it to a number between 0.0 and 1.0.
* The inactive pane hue, saturation, brightness multipliers
have been factored out into their own struct which changes
that set of options to:
```lua
return {
inactive_pane_hsb = {
hue = 1.0,
saturation = 1.0,
brightness = 1.0,
},
}
```
* `window_background_image_hsb` is a new option that can apply
a hue, saturation, brightness transformation to a background
image. This is primarily useful to make a background image
darker:
```lua
return {
window_background_image = "/some/pic.png",
window_background_image_hsb = {
brightness = 0.3,
},
}
```

This includes a script to generate a screenshot from a wezterm
running the default config under X11.
It expects the iTerm2-Color-Schemes to be checked out alongside
the wezterm repo as it uses the dynamic color schemes scripts
to activate the schemes one by one and capture the display.
Upcoming changes to the GUI mean that it will be double
the work to keep maintaining this, and it is already lagging
behind on pane support.
With the Mesa llvmpipe fallback we should be in a pretty
good state to not need another non-GL implementation.
There's a few different knobs to turn, but this
commit turns them and we're now able to respect
opacity settings for both OpenGL/CGL and Metal
renderers.

This is similar in spirit to the work in 4d71a7913a
but for Windows.
This commit adds ANGLE binaries built from
07ea804e62
to the repo. The build and packaging will copy those into the same
directory as wezterm.exe so that they can be resolved at runtime.
By default, `prefer_egl = true`, which will cause the window
crate to first try to load an EGL implementation. If that fails,
or if `prefer_egl = false`, then the window crate will perform
the usual WGL initialization.
The practical effect of this change is that Direct3D11 is used for the
underlying render, which avoids problematic OpenGL drivers and means
that the process can survive graphics drivers being updated.
It may also increase the chances that the GPU will really be used
in an RDP session rather than the pessimised use of the software
renderer.
The one downside that I've noticed is that the resize behavior feels a
little janky in comparison to WGL (frames can render with mismatched
surface/window sizes which makes the window contents feel like they're
zooming/rippling slightly as the window is live resized). I think this
is specific to the ANGLE D3D implementation as EGL on other platforms
feels more solid.
I'm a little on the fence about making this the default; I think
it makes sense to prefer something that won't quit unexpectedly
while a software update is in progress, so that's a strong plus
in favor of EGL as the default, but I'm not sure how much the
resize wobble is going to set people off.
If you prefer WGL and are fine with the risk of a drive update
killing wezterm, then you can set this in your config:
```lua
return {
prefer_egl = false,
}
```

This commit adjusts the window layer to have it try to load EGL
implementations on macOS. This is important as the system
provided OpenGL implementation is deprecated and I wanted to
have a path forward for when it is finally removed.
If EGL fails to initialize, we fall back to the CGL/OpenGL
implementation that we used previously.
I've included binaries built for 64-bit intel from the MetalANGLE
project; here's how I built them:
```
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git --depth 1
git clone https://github.com/kakashidinho/metalangle --depth 1
cd metalangle
PATH=$PWD/../depot_tools:$PATH python scripts/bootstrap.py
PATH=$PWD/../depot_tools:$PATH gclient sync
PATH=$PWD/../depot_tools:$PATH gn --args="is_debug=false angle_enable_metal=true angle_enable_vulkan=false angle_enable_gl=false angle_build_all=false" gen out/Release
PATH=$PWD/../depot_tools:$PATH autoninja -C out/Release
```
Those steps are a little too long to want to put them directly
into the wezterm CI.
It is important for metalangle to be >= 8230df39a5
in order for scaling to be handled correctly when dragging windows
between monitors.

This commit tells the window not to use cocoa native tabs and

Moved the image and hyperlink portion of CellAttributes out
to a separate heap structure, saving 8 bytes per Cell
for the common case of no hyperlink and no image.
`wezterm.action{ExtendSelectionToMouseCursor=nil}` doesn't produce an
`ExtendSelectionToMouseCursor(None)` value because a table value of
`nil` is equivalent to that key not being present and lua sees just
an empty table.
Instead we need to accept `ExtendSelectionToMouseCursor={}` a valid
way to indicate an `Option::None` which is what this commit does.
Due to weirdness that I haven't had a chance to run down, passing
that value through `wezterm.action` doesn't produce the intended
value, so I'm adjusting the docs to show to specify an alternative
syntax for this as part of this commit.

This adds an extra level of indirection to the Mux model;
previously we allowed for Windows to contain an ordered
collection of Tabs, where each Tab represented some kind
of pty.
This change effectively renames the existing Tab trait to Pane
and introduces a new Tab container, so the new model is that
a Window contains an ordered collection of Tabs, and each Tab
can have a single optional Pane.

This commit adds an overline glyph which is simply a line drawn at
the top of the cell.
Due to the way that we use a single glyph for the line layer, this
actually adds a handful of combination glyphs for the different
underline, overline and strikethrough possibilities.
It's getting a bit hefty. Adding another similar attribute in
the future (eg: maybe wiggly underlines?) might prove to be too
much for the simple approach we have right now.
```bash
printf "\x1b[53moverline\x1b[0m\n"
```
This allows setting up shortcuts relative to the final tab in
a window, rather than always being relative to the first.
The default assignment for CTRL+SHIFT+9 is now `ActivateTab=-1`
as a convenient way to always reach the last tab.

This commit adds support for left/right margins and has been
tested against esctest, with a final status of:
```
309 tests passed, 239 known bugs
```
"known bugs" also includes unimplemented features; we have a
similar degree as iTerm2.
As of this commit, we now report as a vt520ish machine to DA1.
I confess to not having read enough of the relevant docs
to know whether this is totally righteous.
This commit allows distinguishing between left and right alt
modifiers at the window layer. So far only macos provides
this additional information.
Expand the logic that decides whether Alt should emit the
composed key or act as the raw key with the Alt modifier flag
set so that we can set that behavior separately for the left
and right modifiers on systems that support it, and use the
existing config for systems that don't support it.
The default settings for these flags is that Left Alt will
send the uncomposed key + Alt modifier while the Right Alt
will behave more like AltGr (which is typically on the RHS
of the keyboard) and send the composed key.
This gives more flexibility by default and hopefully matches
expectations a bit better.

This was originally intended to be swept in and dealt with as part of
adopting CSI-u (refs: https://github.com/wez/wezterm/issues/63) but the
default shift-space mapping is super irritating in vim (refs:
https://github.com/wez/wezterm/issues/126) so it got partially walked
back, but as a consequence we accidentally dropped the modifiers from
those keys (refs: https://github.com/wez/wezterm/issues/213 refs:
https://github.com/wez/wezterm/issues/214).
This commit restores the modifiers for that case.
In addition, since we now have a way to plumb configuration directly
into the term crate, this adds a config option to enable CSI-u for those
that want to use it.
Bound to CMD-K and CTRL+SHIFT-K by default. This also functions
while the output is filling up (eg: `find /` and hit the key binding
to keep pruning the scrollback).

Now that the toml file support is removed, we can directly

intermediate type and use the enum directly.
* AppImage: Support looking for configuration in `WezTerm.AppImage.config` and
`WezTerm.AppImage.home` to support portable thumbdrive use of wezterm on
linux systems
* We now check the github releases section for updated stable releases and show
a simple UI to let you know about the update, with links to download/install
it. We don't automatically download the release: just make a small REST API
call to github. There is no data collection performed by the wezterm project
as part of this. We check once every 24 hours. You can set
`check_for_updates = false` in your config to disable this completely if
desired, or set `check_for_updates_interval_seconds` to an alternative update
interval.
* Added support for OSC 110-119 to reset dynamic colors, improving our support for Neovim.
* Change OSC rendering to use the long-form `ST` sequence `ESC \` rather than
the more convenient alternative `BEL` representation, which was not
recognized by Neovim when querying for color information.
* Fixed Shift-Tab key on X11 and Wayland
* WezTerm is now also available to Windows users via [Scoop](https://scoop.sh/)

This is accessible by right-clicking on the `+` button in the tab bar
and switches to an overlay offering options to spawn tabs and attach
domains.
The intent is to allow the configuration file to expand this list of
options, and on Windows, to auto-populate with the various combinations
of `cmd`, `powershell`, `elevated` and available `wsl` instances, but
for the moment the main value of this feature is the ability to attach
domains that were not set to connect automatically at startup.
This makes things more convenient when launching wezterm via the
gui: it is awkward to have to set up shortcuts that run
`wezterm connect foo`, or to type in the full path to `wezterm` when
you might want to run that manually.
Now you can double-click the icon and right-click the `+` and attach
the domain. (cc: @rjwalsh)
The launcher is a good candidate for being implemented on top of
native context menus where available... but we don't have any
such API plumbed through the `window` crate, so all platforms
get the wonderful terminal based overlay menu right now.

```
{% include toc.html sanitize=true baseurl=p.url html=p.content %}

Then navigate to various pages: the TOC in the LHS inconsistently
