This doesn't really change any behavior, but adjusts the types
such that CSIs that set colors have the potential to track the
alpha channel and that can make it through to the GUI/render layer.
Various color schemes have been duplicated as they have been added to
different scheme collections. They don't always have identical names
(eg: some remove spaces) and sometimes they have very different names
(eg: _bash vs. nightfox, or Miu vs. Blazer).
We already detected duplicates from different collections but previously
we would omit those dupes.
This commit allows us to track those duplicates by recording their
aliases.
When we write out our data, we only include "interesting" alias names;
those where the name isn't trivially identical.
Some scheme collections (eg: iterm2 color schemes) have duplicates
(eg: zenbones and zenbones_light are identical) and we have previously
shipped with both of those names, so we special case to emit dupes
for which we have prior version information in order to avoid
breaking backwards compatibility for our users.
In the doc generation we can generate links to the aliases if we
included them, but also note about the other names and how we don't
include them. That is so that someone searching the docs for say
"_bash" can discover that it is actually a duplicate of "nightfox" and
use nightfox instead.
I needed this while swinging through to the new color scheme data stuff,
but I don't need it any more, and it causes problems with external toml
files.
Record the version in which we first saw a color scheme.
For schemes from iterm2-color-schemes, we just assume that
we've had them forever as it isn't easy to reverse engineer
that metadata.
Everything else is tagged as 'nightly builds only' and I'll update
that to match the version number in the next release.
Newly discovered items will be added with 'nightly builds only'
from this point onwards.
Moved the gradient function into the color module, but kept an alias
under the old name.
Gradients now return color objects.
Converting colors to string now uses rgba format when alpha is not 100%.
This commit expands the toml file definition to include
metadata for the origin url, author and name.
A new sync utility fills out that metadata when it pulls from the iterm2
color schemes repo.
The utility also pulls down the scheme data json maintained by
the Gogh project: https://gogh-co.github.io/Gogh/ and converts
it to wezterm's format.
About 50% of Gogh overlaps with iterm2; we take the iterm2 versions
of those schemes by default because the iterm2 data has more info
about things like cursor and selection colors.
The sync utility is responsible for compiling the de-duplicated
set of scheme data into a form that is used by wezterm and its
docs.
Wraps up the changes from the following diff and allows for the modal
layer (and box model) to use alpha for poly quads.
Change the default background color for pane select to be slightly
transparent.
Avoid using serde for mapping between Lua and Rust for the `Config`
struct.
This improves the build speed of the config crate by 2x; it goes down
from 30 seconds to 9 seconds on my 5950x.
We're now capable of remembering an alpha value for everything
in the palette and the main window theme, but not the tab bar theme.
Whether the alpha is correctly respected at render time is a different
story!

This commit allows the following configuration:
```
wezterm -n --config 'colors = { selection_fg = "clear", selection_bg = "rgba:50% 50% 50% 50%" }'
```
which sets the selection_bg to fully transparent, and selection_bg to
50% transparent gray.
When selection_fg is fully transparent we'll use the normal fg color.
When selection_bg is partially (or fully!) transparent, it will be
alpha blended over the current cell background color.
To support this, the config file will now accept rgba colors specified
as 4 whitespace delimited numeric values. If a value ends with `%` it
is interpreted as a number in the range 0-100. Otherwise, it is
interpreted as a number in the range 0-255. The 4 values are
red, green, blue, alpha.
At this time, only the selection_fg and selection_bg settings accept
alpha values.

When set, the cursor will change to this color during dead key
or leader key processing.
```lua
return {
colors = {
dead_key_cursor = "orange",
},
}
```

Rather than hardcode a fixed default value in the config crate, define
the default as optional and leave it to the font crate to compute
the value.
This is a step towards allow introducing system dependent GUI related
code to resolve/understand the title font: we can't put that directly
in the config crate.
There was a discrepancy between leaving it out of the config
and having it partially initialized; fix that up.
Make the default title font size larger on !Windows, as it
looks a bit better.
We might need to make this larger size mac specific.

Was mistakenly trying to use the windows font because of negative logic.
Tidy up, and prefer the gnome default theme font (Cantarell), but fall
back to DejaVu Sans.
Avoid accidentally scaling the tab bar when using IncreaseFontSize.
Use a "better" default title font based on the platform.
Avoid a gap between bottom of tab button and dividing line at
certain font sizes.
`use_fancy_tab_bar` switches to an alternate rendering of the tab
bar that uses the window_frame config to get a proportional
title font to use to render tabs, as well as rendering a few
additional elements to space out and make the tabs feel more
like tabs.
Computing the number of tabs doesn't respect the alternate font
at this time.
Formatted tab item foreground and background colors are also
not respected at this time.

This simplifies it a bit and exposes the config via the config file;
the following options are possible, each one specifies a color
```lua
return {
window_frame = {
inactive_titlebar_bg = "",
active_titlebar_bg = "",
inactive_titlebar_fg = "",
active_titlebar_fg = "",
inactive_titlebar_border_bottom = "",
active_titlebar_border_bottom = "",
button_fg = "",
button_bg = "",
button_hover_fg = "",
button_hover_bg = "",
}
}
```

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,
},
```

This helps keep the config object a bit smaller and the trace logging
output less verbose.
We now memoize the effective palette in the config, which should shave
off a little bit of time in the renderer.
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,
},
}
```
