OSC 7's standard body is a percent-encoded file:// URL. There isn't an
easy way for us to percent-encode the path ($pwd) component here without
implementing a custom function.
Instead, switch to the kitty-shell-cwd:// scheme, which Kitty introduced
to ease this implementation challenge in shell scripts. It accepts the
path string verbatim, without an encoding.
In Ghostty, we accept both the file:// and kitty-shell-cwd:// schemes,
and we attempt to URI-decode them both, so in practice this is more
about the "correctness" of this protocol than a functional change. It's
also possible we might decide to treat these schemes differently in the
runtime, like Kitty does.
This sort of command is treated as valid by Kitty so we should too. In
fact, it occurs with the example `send-png` script provided in the docs
for the protocol.

This change consolidates all three opt-out shell integration environment
variables into a single opt-in $GHOSTTY_SHELL_FEATURES variable. Its
value is a comma-delimited list of the enabled shell feature names (e.g.
"cursor,title").
$GHOSTTY_SHELL_FEATURES is set at runtime and automatically added to the
shell environment. Its value is based on the shell-integration-features
configuration option.
$GHOSTTY_SHELL_FEATURES is only set when at least one shell feature is
enabled. It won't be set when 'shell-integration-features = false'.
$GHOSTTY_SHELL_FEATURES lists only the enabled shell feature names. We
could have alternatively gone in the opposite direction and listed the
disabled features, letting the scripts assume each feature is on by
default like we did before, but I think this explicit approach is a
little safer and easier to reason about / debug.
It also doesn't support the "no-" negation prefix used by the config
system (e.g. "cursor,no-title"). This simplifies the implementation
requirements of our (multiple) shell integration scripts, and because
$GHOSTTY_SHELL_FEATURES is derived from shell-integration-features, the
user-facing configuration interface retains that expressiveness.
$GHOSTTY_SHELL_FEATURES is intended to primarily be an internal concern:
an interface between the runtime and our shell integration scripts. It
could be used by people with particular use cases who want to manually
source those scripts, but that isn't the intended audience.
... and because the previous $GHOSTTY_SHELL_INTEGRATION_NO_* variables
were also meant to be an internal concern, this change does not include
backwards compatibility support for those names.
One last advantage of a using a single $GHOSTTY_SHELL_FEATURES variable
is that it can be easily forwarded to e.g. ssh sessions or other shell
environments.

I believe this is an upstream bug
(https://github.com/ziglang/zig/issues/23454), where Zig is allowing
extern unions to be tagged when created via type reification. This
results in a CValue that has an extra trailing byte (the tag).
This wasn't causing any noticeable issues for Ghostty for some reason
but others using our pattern were seeing issues. And I did confirm that
our CValue was indeed tagged and was the wrong byte size. I assume Swift
was just ignoring it because it was extra data. I don't know, but we
should fix this in general for libghostty.
See #6957
We were not considering GTK's internal scale factor that converts between
"surface coordinates" and actual device coordinates, and that worked fine
until the scale factor reached 2x (200%).
Since the code is now dependent on the scale factor (which could change
at any given moment), we also listen to scale factor changes and then
unconditionally call `winproto.syncAppearance`. Even though it's somewhat
overkill, I don't expect people to change their scale factor dramatically
all the time anyway...
We can't use nearest neighbor filtering for sampling from the atlas
because we might not actually be doing pixel perfect sampling if the
glyph has been constrained. This will change in the future, but this
will have to be set to linear for now.
This was a hack, and is no longer required since #6877. Users can
explicitly override the GTK GSK renderer by setting the standard GTK env
var `GSK_RENDERER`.

This commit explicitly acquires the GL context in the `unrealize`
signal handler of the GTK Surface prior to cleaning up GPU resources.
A GLArea only guarantees that the associated GdkContext is current for
the `render` signal (see the docs[1]). This is why our OpenGL renderer
"defers" various operations such as resize, font grid changing, etc.
(see the `deferred_`-prefix fields in `renderer/OpenGL.zig`).
However, we missed a spot.
The `gtk-widget::unrealize` signal is emitted when the widget is
destroyed, and it is the last chance we have to clean up our GPU
resources. But it is not guaranteed that the GL context is current at
that point, and we weren't making it current. On the NGL GTK renderer,
this was freeing GPU resources we didn't own.
As best I can understand, the old GL renderer only ever used a handful
of GL resources that were early in the ID space, so by coincidence we
were probably freeing nothing and everything was fine. But with the new
NGL renderer uses a LOT more GL resources (make a few splits and the ID
space is already in the thousands, from GTK!), so we were freeing real
resources that we didn't own, which caused rendering issues. :)
I suspect the above also resulted in VRAM memory leaks (which would be
RAM memory leaks for unified memory GPUs). This potentially relates to
#5491.
The fix is to explicitly make the GL context current in the `unrealize`
handler.

Instead of looking for individual substrings in $GHOSTTY_SHELL_FEATURES,
`str:split` it into a list of feature names and use `has-value` to
detect their presence.

We don't currently support rendering SVG glyphs so they should be
ignored when loading. Additionally, the check for whether a glyph is
colored has been simplified by just checking the pixel mode of the
rendered bitmap.
This commit also fixes a bug caused by calling the color check inside of
`renderGlyph`, which caused the bitmap to be freed creating a chance for
memory corruption and garbled glyphs. This bug was introduced by 40c1140
(#6602) and discussed in #6781.

UTF8 translation using KeymapDarwin requires a buffer and the buffer was
stack allocated in the coreKeyEvent call and returned from the function.
We need the buffer to live longer than this.
Long term, we're removing KeymapDarwin (there is a whole TODO comment in
there about how to do it), but this fixes a real problem today.
Also update shaper test that fails because the run iterator can't apply
that logic since `testWriteString` doesn't do proper grpaheme clustering
so the parts are actually split across multiple cells.
Several other tests are technically incorrect for the same reason but
still pass, so I've decided not to fix them here.
This introduces the concept of a "dist resource" (specifically a
`GhosttyDist.Resource` type). This is a resource that may be present in
dist tarballs but not in the source tree. If the resource is present and
we're not in a Git checkout, then we use it directly instead of
generating it.
This is used for the first time in this commit for the gresource c/h
files, which depend on a variety of external tools (blueprint-compiler,
glib-compile-resources, etc.) that we do not want to require downstream
users/packagers to have and we also do not want to worry about them
having the right versions.
This also adds a check for `distcheck` to ensure our distribution
contains all the expected files.

Discover resourcesdir with `terminfo/g/ghostty`
as well as existing `terminfo/x/xterm-ghostty`.
This allows either terminfo file to be installed,
notably ncurses only provides a `terminfo/g/ghostty`.
