thread 'e2e::sftp::canonicalize_should_either_return_resolved_path_or_error_if_missing' panicked at 'Unexpected result from canonicalize: Err(LibSsh(Sftp(SftpError(2))))', wezterm-ssh/tests/e2e/sftp.rs:615:14
```
We can't currently match that error because the LibSsh SftError(x) error
code is private.
Route logging via the `log` crate because on Windows there is
no stderr visible to libssh.
libssh will override any explicitly set options when it parses
the config file, so we need to apply those after we've loaded it.
A recent cargo update caused openssl-sys to do a minor semver update
from 0.9.71 -> 0.9.72, but that release downgraded from openssl 3
to openssl 1 to resolve a performance regression:
<https://github.com/sfackler/rust-openssl/pull/1578>
That in turn caused libssh to fail to build because the ENGINE
feature required by libssh isn't compiled in in openssl-src 1
crate when vendoring on windows.
For now, my libssh git repo is constrained to openssl-sys 0.9.71,
and we're pointing to that from the wezterm repo.
For some reason, winapi's HANDLE type isn't compatible with the core
rust ffi HANDLE type when cross compiling.
This commit adds some casts.

The texture coordinates into the source image weren't quite right;
previously we'd do this math:
num_cells = (image_size / cell_size).ceil()
delta = num_cells / image_size
that would result in the image being stretched to fit across the rounded
up number of cells, leading to a distored image.
This commit changes the delta calculation to be based on the remaining
number of pixels in a given dimension relative to the cell size.

This code was partially replicating the initial window setup
where we didn't necessarily know the dpi, but in the context
where this is run, we do know the dpi for the window, so
let's consistently use that number throughout.

In the mux layer, we have some code that takes a `Child` and then
does a bit of naughty reaching through the abstraction to get at
the pid/handle of the child so that we can send it signals even
if the child is itself mutably (and thus exclusively) borrowed
for the purposes of waiting.
That worked fine for local processes spawned in the mux, but we also
use LocalPane to wrap around arbitrary `Child`ren, such as Ssh,
that are not local and that don't have a local process id, which
meant that this hack wouldn't work for them.
To make things a bit worse, those ssh ptys were used to ssh2 days
where we didn't have a way to signal the remote process and just
did nothing, leading to confusing situations such as
https://github.com/wez/wezterm/issues/1197
This commit graduates the hack mentioned in the first paragraph
to its own ChildKiller trait. This makes the concept of waiting
for the Child distinct from signalling it and explicitly allows
getting a separate object that can be used for signalling.
With that in place, we're forced to implement something appropriate
for the ssh pty implementations; one in the pty crate itself,
one in wezterm-ssh and the wrapper that we use in the mux crate.
The upshot of this is that the `CloseCurrentPane` action now operates
correctly on panes that were the result of split operations.
The intent is to workaround what appears to be an i3 bug.
Not totally sure this is a good change, but let's try it!
Might also help with an issue on macos.

While the description at DEC STD-070 04-31 does not mention Left Right
Margin Mode (it does mention the left and right margins), the code at
04-34 sets it to FIXED (the reset state, the set state is SETABLE).
