f03dc68f96 move shape & quad caching to hang off Line appdata
Remove the faulty cache key stuff and hang references to the cached
data directly off the underlying Line.  That makes the association
between the the Line and the data O(1) plus some basic cache
invalidation checks.

Adjust the shape cache portion of this to use the same ID for the
shape, so that things that invalidate just the quads (such as cursor
movement when not composing, and selection) only need to recompute
the quads without re-shaping.

b7b1e4020a revise Pane line related funcs
Adds Pane::for_each_logical_line_in_stable_range_mut and
Pane::with_lines_mut which allow iterating mutably over lines.

The idea is that this will allow the renderer to directly cache
data in the Line via its appdata without having to build cumbersome
external caching logic and managing cache keys.

This commit just swaps the implementation around for localpane
and sanity checks that the renderer functions.

Various overlays and the mux client don't properly implement these
yet and current warn at compile time and panic at runtime.

To follow is the logic to cache the data and make sure that it
works the way that I think before converting the other Pane
implementations.

39adbb984d Pane::search: expose range, limit. Limit quickselect by default
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.

7be01110ca termwiz: avoid cluster -> vec conversions in a few more cases
This reduces the resident memory by another ~10% because it avoids

8002a17242 term: default to cluster storage
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.

751dd460da term: compress rows as they move into scrollback
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.

a282d07776 mux: add titles to mux window and tab objects
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.

d8cfdae27b avoid ping-ponging focus updates with multiple windows
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.
