This makes those fields usable in `wezterm cli list --format json`.
This doesn't change the ABI of the mux protocol, but prior to
this commit, those fields were always 0.

Just clamp it to the current physical, non-scrollback portion
of the screen.
This avoids a panic but doesn't address the screen size mismatch
in the associated issue.

The recent work on the scrollback made it easier to constrain the
search region, so expose those parameters to the Pane::search
interface and to the mux protocol.
Use those new parameters to constrain quickselect search to
1000 rows above and below the current viewport by default, and
add a new parameter to QuickSelectArgs that allows overriding that
range.
A follow-up commit could make the search/copy overlay issue a series
of searches in chunks so that it avoids blocking the UI when
searching very large scrollback.

This reduces the resident memory by another ~10% because it avoids
keeping as many runs of whitespace.
Runtime for `time cat enwiki8.wiki` is still ~11-12s, resident: 530K

The previous commit added the option to convert the storage to
the cluster format. That saves memory as rows are moved to scrollback,
but makes scrolling back more expensive due to that conversion.
This commit adds a fast(ish) path for the common case of simply
appending text to a new line before it gets scrolled: the default
format for lines in the screen is now the cluster format and,
provided that the cursor moves from left to right as text is
emitted, can simply append to the cluster storage in-place
and avoids a conversion when the line is moved to scrollback.
This improves the throughput of `time cat enwiki8.wiki` so
that the runtime is typically around 11-12s (compared to 9-10s
before introducing cluster storage). However, this is often
a deal of variance in the measured time and I believe that
that is due to the renderer triggering conversions back to
the vec storage and introducing slowdowns from the render side.
That's what I'll investigate next.
This commit causes lines to be "compressed" (really, just translated
to the new clustered line storage variant) as they move into scrollback.
The memory savings are significant for large scrollback:
`wezterm -n --config scrollback_lines=1000000`
`time cat enwiki8.wiki`
before: ~9s, Resident: 2.1G
after: ~15s, Resident: 620K (!)
The performance impact is non-trivial, and I will dig into that
next.

Previously, the mux layer had no internal understanding of titles other
than the Pane::get_title method to return state from a pane.
Users have asked for ways to explicitly set titles on windows and tabs,
so this commit is a step towards that.
The mux window and tab objects now store a title string.
The terminal layer now emits Alert::WindowTitleChanged when the window
title is changed via eg: OSC 0 or OSC 2.
The mux layer will respond to Alert::WindowTitleChanged by resolving the
window that corresponds to the source pane and amending its title.
The MuxWindow and MuxTab objects now provide accessor methods for the
title.
TabInformation (as used by format-tab-title and format-window-title) now
exposes the underlying window_id as well as tab_title and window_title.
The tab title can be changed via the lua MuxTab type, but there is not
currently an escape sequence associated with this.
The defaults for format-tab-title and format-window-title don't
currently consider these new title strings.

This enables tentative support for https://sw.kovidgoyal.net/kitty/keyboard-protocol
It's only been lightly tested with the notcurses-input program and
eyeballed against a few random keypresses in kitty running
`printf "\x1b[=11u" ; od -c`
I tried with neovim, but it doesn't seem like the version available
in Fedora 36 supports this yet.

Main thing to note here is that the open crate has deprecated
open::that_in_background, but made open::that non-blocking.
I think this is OK, but I'm a little cagey about what will
happen with this on Windows. We may need to spawn our own
thread for this if things go awry.
Avoid using serde for mapping between Lua and Rust for the `Config`
struct.
This improves the build speed of the config crate by 2x; it goes down
from 30 seconds to 9 seconds on my 5950x.
I want to make some changes to the scrollback structure that
first require routing some operations through an accessor
method, so this commit does that.
It should have no functional difference.
I've bundled this into termwiz's UnicodeVersion type as that is
a similar concept that is already routed through to the appropriate
function.

I'm not totally sure this is all there is to it, but in #1850
the response is showing up after vim was exited, so it seems like
it didn't fully receive these responses.

We're now capable of remembering an alpha value for everything
in the palette and the main window theme, but not the tab bar theme.
Whether the alpha is correctly respected at render time is a different
story!

The bug here was that each paint call in a window would update
the focus state of its panes to reflect the one that had focus.
However, it didn't account for the actual window focus; it would
just assume that it was focused.
The result was that the perceived focus would alternate between each of
the windows in the wezterm process, and if you were running an
application that had enabled focus tracking, those events could cause a
repaint and drive up the CPU utilization.
This commit addresses that by gating the focus update to only occur
when we have the focus, and for extra safety, avoid generating focus
events at the terminal layer if the new state matches the current state.

Go directly to the underlying env_logger crate, as pretty_env_logger
hasn't been updated in some time, and I'd like to be able to redirect
the log output to a file more directly, and that feature is in a newer
version of the env logger than pretty_env_logger was pulling in.
This persuades vim to set ttymouse=sgr by default.
We're carefully sitting below 279 which triggers
some queries for things that we don't respond to yet.

I think this looks less jarring than the yellowish selection color,
and the translucency looks nicer than changing the fg color completely
black as it did previously.
* gui: improve mouse text selection
* implement mouse press capture between the terminal and UI, so when you
start selecting text from the terminal the tabs won't activate and
vice-versa
* selecting from the top and bottom lines won't scroll the viewport
anymore, it will only scroll if the mouse is moved out of line bounds
* change cell selection so that it behaves like text selection usually
does in other popular software

Previously, we'd just default the resize quirk on for all programs on
Windows.
That pessimizes the otherwise fine behavior of `wezterm ssh` or mux
connections to unixy platforms.
This commit moves the quirk out of the config trait and makes it
a runtime property of the terminal, and then arranges for it
to be set when we know that we set up a conpty for the terminal.
