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.
As recommended in
https://github.com/ghostty-org/ghostty/pull/4927#issuecomment-2585003934,
adds a config option `maximize` for starting a window in a maximized
state in terms of window properties. Also adds a `toggle_maximize`
keybind to allow users to manually toggle this feature on and off.
It might make more sense to make this an optional config value so that
we don't toggle the state off if the WM already handles that for us, but
I'll let a reviewer decide.

Previously, the logic navigated to the second-to-last tab instead of the
last tab due to an off-by-one error. This updates the implementation so
that the index calculation to accurately target the last tab. In the
`gotoLastTab` method there was a decrement in the number of max number
of tabs and another increment in the `goToTab` method to get the actual
tab index.
Fixes#5022
The CSI SGR sequence (CSI m) is unique in that its the only CSI sequence
that allows colons as delimiters between some parameters, and the colon
vs. semicolon changes the semantics of the parameters.
Previously, Ghostty assumed that an SGR sequence was either all colons
or all semicolons, and would change its behavior based on the first
delimiter it encountered.
This is incorrect. It is perfectly valid for an SGR sequence to have
both colons and semicolons as delimiters. For example, Kakoune sends the
following:
;4:3;38;2;175;175;215;58:2::190:80:70m
This is equivalent to:
- unset (0)
- curly underline (4:3)
- foreground color (38;2;175;175;215)
- underline color (58:2::190:80:70)
This commit changes the behavior of Ghostty to track the delimiter per
parameter, rather than per sequence. It also updates the SGR parser to
be more robust and handle the various edge cases that can occur. Tests
were added for the new cases.

Piggybacking on the logic introduced PR
https://github.com/ghostty-org/ghostty/pull/3997, this patch prevents
mouse motion events with the same cursor position triggered by the
window title updating from un-hiding the mouse even when
`mouse-hide-while-typing` config item is true.
Two major changes:
1. Hiding uses `NSApp.hide` which hides all windows, preserves tabs, and
yields focus to the next app.
2. Unhiding manually tracks and brings forward only the windows we hid.
Proper focus should be retained.
There's one behavioral change here. Before this patch, if
`gtk-titlebar=false` we _never_ created a headerbar. This explicitly
contradicted the comments in the source, and the documentation for
`gtk-titlebar` imply that if a window starts out without a titlebar it
can be brought back later with the `toggle_window_decorations` keybind
action.
After this patch, a headerbar is always created, but if
`gtk-titlebar=false` or `window-decoration=false` it's immediately
hidden.
I'm not sure how this interacts with the current SSD/CSD detection that
seems to happen when running Ghostty on non-Gnome DEs so it'll be
important to get #4724 merged (plus any follow ups) to enable more
explicit control of SSD/CSD.

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.
A "size-limit" function has been implemented for GTK which calls
gtk_widget_set_size_request() to set the minimum widget/window size.
Without
this function, it's left to GTK to set the minimum size which is usually
a lot larger than the documented 10x4 cell minimum size. This doesn't
fix the
issue completely as GTK retains the final say in how small a window can
be
but it gets closer.
Resolves: #4836
