This commit is quite large because it's fairly interconnected and can't
be split up in a logical way. The main part of this commit is that alpha
blending is now always done in the Display P3 color space, and depending
on the configured `window-colorspace` colors will be converted from sRGB
or assumed to already be Display P3 colors. In addition, a config option
`text-blending` has been added which allows the user to configure linear
blending (AKA "gamma correction"). Linear alpha blending also applies to
images and makes custom shaders receive linear colors rather than sRGB.
In addition, an experimental option has been added which corrects linear
blending's tendency to make dark text look too thin and bright text look
too thick. Essentially it's a correction curve on the alpha channel that
depends on the luminance of the glyph being drawn.

This PR attempts to reduce the flash caused by the ghost emoji in the
title bar when opening new windows.
## Changes:
- Initialize `SurfaceView.title` with empty string instead of ghost
emoji
- Simplify title computation logic in `TerminalView`
- Adding a 500ms fallback timer for "👻"
- Canceling timer if title is set
## Current Status:
While these changes reduce the initial ghost emoji flash, there's still
a brief moment where a folder emoji appears alone in the title bar when
opening a new window. This suggests there might be a race condition or
timing issue with how the title is being set and updated.

Would appreciate feedback on the remaining flash issue and suggestions
for further improvements.

This commit fixes two issues:
1. `libghostty` must not override ctrl+key inputs if we are in a preedit
state. This allows thigs like `ctrl+h` to work properly in an IME.
2. On macOS, when an IME commits text, we strip the control modifier
from the key event we send to libghostty. This is a bit of a hack but
this avoids triggering special ctrl+key handling.
Fixes#4539
AquaSKK is a Japanese IME (Input Method Editor) for macOS. It uses
keyboard inputs to switch between input modes. I don't know any other
IMEs that do this, but it's possible that there are others. Prior to
this change, the keyboard inputs to switch between input modes were
being sent to the terminal, resulting in erroneous characters being
written.
This change adds a check during keyDown events to see if the input
source changed _during the event_. If it did, we assume an IME captured
it and we don't pass the event to the terminal.
This makes AquaSKK functional in Ghostty.
This changes quit signaling from a boolean return from core app `tick()`
to an apprt action. This simplifies the API and conceptually makes more
sense to me now.
This wasn't done just for that; this change was also needed so that
macOS can quit cleanly while fixing #4540 since we may no longer trigger
menu items. I wanted to split this out into a separate commit/PR because
it adds complexity making the diff harder to read.
When unset, we use Sparkle's default behavior, which is based on the
user's preference stored in the standard user defaults.
The rest of the previous behavior is preserved:
- When SUEnableAutomaticChecks is explicitly false, auto-updates are
disabled.
- When 'auto-update' is set, use its value to set Sparkle's auto-update
behavior.

Renames the top/bottom directions of `goto_split` to up/down. I have
tested this on linux (nixos) but given that `goto_split` is broken on
linux anyway (#2866) there's not a whole lot to test.
I have no way to build on macOS so I can't verify that I've changed
everything correctly for that.
Closes#3237

On mouseExit we sent a cursor position event with (-1, -1). Negative
values are meant to indicate that the cursor is not on the surface. The
magnitude of the values are irrelevant. However, we never reset the
cursor position on mouseEnter.
This has the effect of the previous cursor position being stuck outside
the viewport which makes certain things such as `button` mouse reporting
not report until the mouse is moved.
This commit sends the correct cursor position event on mouseEnter.

I'm not fully sure if this will fix this issue since I can't reproduce
it but I don't see a downside to doing this and it might fix it.
Fixes#3072
Previously, when `window-theme = auto`, the appearance was delayed
enough on the DispatchQueue that the window was already visible. This
would result in the window appearing with the wrong appearance before
switching to the correct one.
For annoying reasons, we can't set the NSApplication.shared.appearance
in `applicationDidFinishLaunching` because it results in a deadlock with
AppKit.
This commit moves to set the `NSWindow.appearance` in `windowDidLoad`
(and any config sync) to ensure that the appearance is set before the
window is visible.
This is probably the right solution anyways because this allows windows
with different background colors to each have their own distinct
appearance.
## Description
Introduce a setting allowing to customize the behavior of the quick
terminal when it loses focus. By default, the quick terminal will
automatically hide. However, you can now configure it to remain open by
setting `quick-terminal-autohide: false`.

Ghostty now has a release channel build configuration. Current valid
values are "tip" and "stable" but I imagine more will be added in the
future.
The release channel is inferred whether the version we specify with the
`-Dversion-string` build flag has a prerelease tag or not. If it does,
the release channel is "tip". If it doesn't, the release channel is
"stable".
This also adds a configuration to specify the release channel for
auto-updates for the macOS application.
Fixes#2900
It's possible for moveFocus to infinite loop if the surface view we're
trying to move focus to NEVER gets attached to a window. This can happen
if the window is destroyed.
I think this issue should be more systemically fixed so it can't happen
but this workaround for now prevents moveFocus from being an infinite
loop source for the time being.
Fixes#2848
The proper way to convert a unicode scalar in Swift is to use the
`String` initializer that takes a `UnicodeScalar` as an argument. We
were converting a number to a string before, which is incorrect.
The prior light/dark mode awareness work works on surface-level APIs. As
a result, configurations used at the app-level (such as split divider
colors, inactive split opacity, etc.) are not aware of the current theme
configurations and default to the "light" theme.
This commit adds APIs to specify app-level color scheme changes. This
changes the configuration for the app and sets the default conditional
state to use that new theme. This latter point makes it so that future
surfaces use the correct theme on load rather than requiring some apprt
event loop ticks. Some users have already reported a short "flicker" to
load the correct theme, so this should help alleviate that.
