This change also allows removing the dep on the palette crate,
which I found to be difficult to use (API changed often, and relied
on a lot of `.into` that was hard to follow and reconcile across
upgrades). We already pulled in the csscolorparse crate as an indirect
dep of colorgrad, so we can replace the color conversion we need for
sixel with that crate while we're in here.

For a sequence like `e U+20d7` the intent is to render the `e` with
a vector arrow over the top.
This is typically implemented by fonts as an `e` followed by the
vector glyph (or vice versa), where either one of those may have
a zero advance so that the two elements are combined.
There were two problems here:
* During shaping we'd see the zero advance and assume that the entry
was useless and skip it
* During rendering, if we didn't think it had any cell width, we'd
not render it
Cursoring through that particular sequence can hide the vector
mark if the cursor is set to the default block cursor due to annoyances
in how the block cursor is rendered (it changes the fg color to match
the bg, but for elements outside where we think the cursor is, this
makes those elements invisible).

The issue is that we work hard to match the keys pre-composition,
but for French and Norwegian layouts ALT-number are valid,
useful punctuation keys. It's awkward to make exceptions for
ALT keys when matching assignments, especially on macOS, and
the simplest thing to do is simply to remove the assignments
and leave it to our users to add their own if they want them.
The ctrl-shift and cmd based assignments are generally much
easier to keep, because those key combinations are not widely
used default mappings on any keyboard layout.

`ScrollByPage` can accept non-integer values in the configuration.
This allows fractional page scrolling, such as by half a page.
The default remains the same, at 1 page.
user vars were stubbed out. This commit adds storage for them
in the mux client and adds a new notification that publishes each
var as it is changed. That differential stream is applied to the
storage in the mux client when it is received.
```lua
local wezterm = require 'wezterm'
wezterm.on("update-right-status", function(window, pane)
local woot = pane:get_user_vars().woot
window:set_right_status(tostring(woot))
end);
return {
unix_domains = {
{name="unix"},
},
}
```
then running:
* `wezterm connect unix`
* in that session: `printf "\033]1337;SetUserVar=%s=%s\007" woot `echo -n nice | base64``
causes `nice` to show in the status area.

If we know that the remote host is a unix system, and that it uses some
version of the posix shell, then we can adjust our command line to cd to
the requested directory (as set by OSC 7) and then exec the requested
command.
That's what SshDomain::assume_unix indicates and what this commit does.
This puts us in a better position for the future to be able
to configure whether we use wezterm, tmux or no multiplexing.
Today we allow wezterm or no multiplexing.
Add docs on this new setting.

When spawned with no WEZTERM_UNIX_SOCKET environment set,
we now prefer to resolve the gui instance, falling back to
the mux if it doesn't look like the gui is running.
`wezterm cli --prefer-mux` will use the original behavior of
trying to resolve the path from the unix domain in the config.
The old way would remove the icon form the dock. it needs greedy-latest because the cask is declared as `latest`.

This commit adds a couple of helper methods that provide insight into
the state of the keyboard layer.
The intent is for users to add status information about the keyboard
state.
This commit also ensures that we schedule an update when the leader
key duration expires, and ensures that we close out the leader state
for an invalid key press.
refs: #686closes: #688
```lua
local wezterm = require 'wezterm';
wezterm.on("update-right-status", function(window, pane)
local leader = ""
if window:leader_is_active() then
leader = "LEADER"
end
local dead = ""
if window:dead_key_active() then
dead = "DEAD"
end
window:set_right_status(leader .. " " .. dead)
end);
return {
leader = { key="a", mods="CTRL" },
colors = {
dead_key_cursor = "orange",
},
}
```
When set, the cursor will change to this color during dead key
or leader key processing.
```lua
return {
colors = {
dead_key_cursor = "orange",
},
}
```

Previously, we'd take a couple of guesses at how to map the key
to a utf8 value, but! the keyboard state has a method that can tell
us what to use.
This is important in non-latin keymaps where, for example, the `c`
key generates cyrillic small letter es and we'd end up sending
CTRL + that through to the terminal when CTRL is held down.
If we get the utf8 string from the keyboard layer then we get
CTRL+c instead, and that is what we want.

Certain keys are "handled" by the IME through it generating a "noop"
command.
That's not super useful for us, so this commit detects the noop case
and then treats it as though the IME didn't handle the input event.
While implementing the above fix, I realized that the same technique
could be used more generally to return processing to our main input
handling for the various selectors that we do recognize: we were
essentially inferring the original key combinations based on the
selector which is not scalable and potentially lossy.
We can't capture CTRL-ESC this same way, as that key combination
is magical and is routed to the callback without generating any
key events.

We only need to recompute when the tab content changes, or when
the window is resized, plus invalidations of the shape cache
of texture atlas filling up.
Hover events don't need to re-shape.
We can now also place the tab bar at the bottom of the screen again.
This adds string serialization for the keycode and modifiers as
used in the config.
We can't simply tell the base types to serialize in this form because
we may serialize and pass those via the mux protocol and the default
derived serializers are more efficient for that purpose.
This allows:
```lua
local wezterm = require 'wezterm'
return {
keys = {
{key="a", mods="ALT", action=wezterm.action{SendKey={key="b"}}}
},
}
```
to parse: previously, wrapping `SendKey` in `wezterm.action` would fail
to round-trip the the `SendKey` and lead to an error loading the
config.
Add `get_foreground_process_name` to both Pane and the lua wrapper.
Add `foreground_process_name` and `current_working_dir` fields to
`PaneInformation`. In order for those to be dynamically fetched,
switch the lua conversion for `PaneInformation` to be a UserData
with field access methods. It's a little more verbose but allows
us to lazily compute these two new fields.

This is really a timing issue: if shift-click extension of the mouse
selection is used, the user may release the mouse button slightly
after the SHIFT key (which is fine) or vice versa (which was not
previously matched)

This commit expands quick select mode so that you can trigger it
with distinct sets of patterns (eg: urls on one key assignment,
hashes on a different key assignment), different alphabets,
and lastly, the option to perform a different action from
the default copy action.
You can pair this with `action_callback` to run lua code to
do something with the selected text.
This commit also adds `wezterm.open_with`, a helper function
for opening documents/URLs.

Remove special case for blocks where we switched it out for a blank
sprite and instead varied the cell background.
We now always render a matching cursor sprite as a separate layer
over the top of the text background color, but below the text
foreground layer.
This is preparing for https://github.com/wez/wezterm/issues/1432
Make bar/line cursors use the text foreground color when reverse
video cursors are enabled, per @VKondakoff:

`wezterm.font` and `wezterm.font_with_fallback` can now specify
harfbuzz_features and freetype load/render target and flags as
options on a per-font basis.
This allows you to do things such as adjust shaping (eg: ligatures) or
rendering (eg: disable bitmaps, or adjust hinting) for a single font in
a fallback rather than globally for all fonts.
This commit teaches `RgbColor::from_rgb_str` to support
colors in the form `hsl:235 100 50`, an HSL colorspace
color specification.
While banging my head on why my test wasn't passing, I realized
that this was producing 10 bpc color and the code to convert
those to RGB was incorrectly multiplying conversion terms!

Finally getting around to fixing this usability wart: this commit
changes the behavior of Window closing so that you can close a window
containing multiplexer panes without prompting and without killing
off those panes.
This is achieved through some plumbing:
* The mux can now advise Domains about an impending window closure,
giving them the opportunity to "do things" in readiness.
* The mux client domain informs the container ClientPane instances
to ignore the next Pane::kill call, which would otherwise inform
the mux server to kill the remote pane
* Pane:can_close_without_prompting now requires a CloseReason.
* ClientPane's can_close_without_prompting impl allows Window closing
without prompting on the assumption that the ignore-next-kill hack
above is working
refs: #848
refs: #917
refs: #1224
This commit adds plumbing to support mapping the process tree to
lua objects which in turn allows a new `mux-is-process-stateful`
event to be defined by the user for finer control over closing
prompt behavior.
