The default is true, which means that adjusting the font size will
cause the window to resize to preserve the number of rows/cols in
the terminal.
When set to false, the window size is preserved and the number of
terminal rows/cols is adjusted instead.

I started this a while ago; it's pretty time consuming to produce
accessible and usable documentation for this sort of stuff, so
this isn't yet complete, but in the interest of avoiding additional
bit-rot, let's get this up.

The heart of this issue was that the resize callbacks have two
layers of state; one in the low level window and one in the application
level window.
On Windows, the system triggers the low level callback prior to
opengl being initialized. Since the application level depends on
the opengl state, there are some code paths where it NOPs and
returns early if opengl isn't yet initialized.
When the system-wide display scaling is set to say 200%, the application
layer can't know the effective DPI of the window it is creating because
it doesn't know which monitor will be used or what its DPI will be.
New windows are created at the default DPI of 96, and we rely on the
resize events to detect the actual DPI and adjust the scaling in
the window.
The early call of the resize callback meant that the low level and
application level size/dpi state was out of sync and the result was
that the window had half as many pixels as it should, but that the
terminal model was still sized as though it had the correct amount
(twice as many as visible). This resulted in the window being too
small for the viewport.
The resolution is simple: we now suppress emitting the resize processing
until opengl has been initialized.
The test scenario for this is:
* Set system scaling to 100%
* Launch wezterm
* Set system scaling to 200%
* Observe that wezterm scales to match
* Press CTRL-SHIFT-N to spawn a new window
* Observe that the new window size matches the other window (previously
this one would be half the size)
While I was looking at this, I noticed that the manifest didn't
match the DPI awareness that we have in the code, so update that.

This appears to have been broken since the introduction of mouse
assignments :-/
This commit adds Pane::is_alt_screen_active so that the gui layer
can tell whether the alt screen is active, and allow passing down
the event.

This persuades the CI to install both the arm and intel flavors
of the rust toolchain on macOS, and the deploy script to generate
a universal binary.

I've seen a number of people copy and paste the example that runs
`top` and be confused by it, so try to make it a bit clearer how
to get a regular split with a shell inside it.
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.
