39dd4cdd82 Add config options to control various cache sizes
These are more for low level testing than they are intended
for users to play with, so they are deliberately undocumented
at this time.

598f5081ec respect invisible text attribute
This is a weird attribute TBH.

xterm seems to replace the cells with spaces: copying and pasting
results in spaces.

Kitty ignores it.

VTE doesn't render it but allows copying and pasting.

The latter is now also the behavior in wezterm.

c0fff4e843 Add wezterm.gui.default_key_tables()
This provides a means for more easily extending the default key
tables without forcing the user to recreate the entire config
for themselves.

wezterm.gui.default_keys is also added by this, but it is likely
not as useful.

026b9e3577 fix hyperlink underlines
There were two problems:

* We weren't correctly invalidating when the hover state changed
  (a recent regression caused by recent caching changes)
* We'd underline every link with the same destination on hover,
  not just the one under the mouse (longstanding wart)

Recent changes allow the application layer to reference the underlying
Lines directly, so we can restore the original and expected
only-highlight-under-the-mouse by switching to those newer APIs.

Adjust the cache values so that we know to also verify the current
highlight and invalidate.

I was a little surprised to see that this also works with mux client
panes: I was expecting to need to do some follow up on those because
they return copies of Line rather than references to them. That happens
to work because the mux client updates the hyperlinks at the time where
it inserts into its cache. The effect of that is that lines in mux
client panes won't update to new hyperlink rules if they were received
prior to a change in the config.

ea1513f480 Search incrementally in chunks of 1000 lines, show progress
This makes the search feel more responsive.

We search from bottom to top so that we show the more recent results
first, but for the sake of efficiency when accumulating result chunks
we need to reverse the order of the results vec from how it was
previously.

Each result chunk is loosely ordered from top to bottom, so we sort
it and reverse it: results[0] is the bottom-most result.

New rows are accumulated on the end of the result array; this is
not only more efficient, but it preverses the match result number
ordering.

The next/prior functions need to be swapped to account for this change
in result order.

1b9ea2de3f change text cursor to fa_lock when entering passwords
There are caveats to determining this, but when we think
password entry is enabled, switch the cursor to the font-awesome
lock glyph instead of the normal cursor sprite.

fa_lock is used because it is monochrome and can thus be tinted
to the configured cursor color, and it respects blinking/easing.

14c613a064 add Pane::get_metadata
The idea here is that different kinds of panes may want to expose
additional metadata to lua scripts. It would be a bit weird to add
a Pane method for each of those and plumb it all the way through
the various APIs, so just allowing a pane impl to return a dynamic
value (likely an Object) allows a bunch of flexibility.

This commit exposes the clientpane is_tardy boolean and the time
since the last data was recevied (since_last_response_ms) from
the mux client pane implementation: these are used to show the
tardiness indicator in the client pane.

Exposing this data enables the user to add that info to their
status bar if they wish.

ed731a0d8d Add CharSelect modal for emoji/nerdfont/unicode input
CTRL-SHIFT-U is a new default key assignment for this new modal.
It opens up a fuzzy searchable browser that defaults to showing
emoji/emoticons.  The category can by cycled through the suggested
emoji categories using CTRL-r.  Unlike the system emoji palette,
wezterm includes a category for nerdfont symbols, and another
that is a list of all unicode codepoint names, so you should be
able to browse for pretty much any codepoint you can think of.

The modal also allows fuzzy searching based on:

* The official unicode name
* The github shortcode
* codepoint value in hex

so if you know the codepoint value but not the name, you can
still find a way to input what you're looking for.

Pressing Enter will copy the selected item to the clipboard
send it to the active pane, and cancel the modal. You can therefore
repeat the insert by simply pasting.

I plan to add frecency to this in a later commit: that way the
frequently/recently used selections will show in a category of
their own and make it easier to re-input them.

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.

00ddfbf9b8 perf: cache quads by line
Introduces a heap-based quad allocator that we cache on a per-line
basis, so if a line is unchanged we simply need to copy the previously
computed set of quads for it into the gpu quad buffer.

The results are encouraging wrt. constructing those quads; the
`quad_buffer_apply` is the cost of the copy operation, compare with
`render_screen_line_opengl` which is the cost of computing the quads;
it's 300x better at the p50 and >100x better at p95 for a full-screen
updating program:

full 2880x1800 screen top:

```
STAT                                             p50      p75      p95
Key(quad_buffer_apply)                           2.26µs   5.22µs   9.60µs
Key(render_screen_line_opengl)                   610.30µs 905.22µs 1.33ms
Key(gui.paint.opengl)                            35.39ms  37.75ms  45.88ms
```

However, the extra buffering does increase the latency of
`gui.paint.opengl` (the overall cost of painting a frame); contrast the
above with the latency in the same scenario with the current `main`
(rather than this branch):

```
Key(gui.paint.opengl)                            19.14ms  21.10ms  28.18ms
```

Note that for an idle screen this latency is ~1.5ms but that is also true
of `main`.

While the overall latency in the histogram isn't a slam dunk,
running `time cat bigfile` is ~10% faster on my mac.

I'm sure there's something that can be shaved off to get a more
convincing win.

          orientation = {
            Radial={
              cx = 0.75,
              cy = 0.75,
              radius = 1.25,

          },
        }
      },
      width="100%",
      height="100%",

```

setting noise=0 "fixed" it, so this commit localizes that fix

28d803e3f4 refine dual source blending / subpixel aa and RGBA color interaction
Previously, we'd unconditionally enable dual source blending for the
text foreground layer when rendering. That meant that if the user had
configured the fg color to include an alpha value it would get "stamped
through" the draw all the way to the background, making that whole pixel
take on that alpha value rather than allowing it to blend through the
way you might expect.

In prior releases that didn't matter, but since we now allow configuring
the fg color with alpha, and allow using escape sequences to set the fg
for a span to something with alpha, there is now a much higher chance of
something looking weird.

Dual source blending is only really needed for subpixel-aa and that
isn't enabled by default.

This commit changes the behavior to use regular alpha blending if the
main config (rather than a per-font override) hasn't set the freetype
load/render target to one that enables subpixel-aa.

That means that alpha channel values work as expected for fg color
by default.

If you want to enable subpixel-aa you need to enable it globally
and be aware that it will cause weirdness when trying to use alpha
channels for the fg text color.

The docs now also indicate this behavior.

This limitation could be removed by making text rendering significantly
more complex and I don't fancy doing that at this time.

its current size and the size of a newly added tab and resizes to

      -- start selecting by zone: both the start point and the cursor
      -- position will be expanded to the containing zone and the union
      -- of those two will be used for the selection

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.

6d61ceac47 search: fix incorrect highlight in search results
If you typed "cat" in the search, the chances are that wezterm
would kick off a search for "c" before you finished typing,
then "ca" and then finally "cat".

There was a race:

clear by_line highlights,
queue search for "c"
clear by_line highlights,
queue search for "ca"
clear by_line highlights,
queue search for "cat"
accumulate highlights for "c" into by_line
accumulate highlights for "ca" into by_line
accumulate highlights for "cat" into by_line

so the final result was a superposition of all of those results,
which was weird!

The fix is simple: clear by_line when we get the results of
an async search.

d5d161b510 termwiz: add clustered line storage for line
Adds the option to use an alternative clusted line storage for
the cells component of the line.

This structure is not optimal for mutation, but is better structured
for:

* matching/extracting textual content
* using less memory than the prior simple vector

For some contrast: the line "hello" occupies 5 Cells in the cell based
storage; that 5 discrete Cells each with their own tiny string
and a copy of their attributes.

The clustered version of the line stores one copy of the cell
attributes, the string "hello" and some small (almost constant size)
overhead for some metadata.  For simple lines of ascii text, the
clustered version is smaller as there are fewer copies of the cell
attributes.  Over the span of a large scrollback and typical terminal
display composition, this saving is anticipated to be significant.

The clustered version is also cheaper to search as it doesn't require
building a copy of the search text for each line (provided the line is
already in clustered form).

This commit introduces the capability: none of the internals request the
new form yet, and there are likely a few call sites that need to be
tweaked to avoid coersion from clustered to vector form.

355f3d3975 fix reloading the global config when the appearance changes
We didn't actually update the global config, just the per-window
configs, which led to weird stale throwbacks to earlier versions
of the config when spawning windows or new panes.

Fix that up by explicitly reloading the global config when the
window appearance is changed.  That isn't ideal as we will reload
once per window, but it's "OK".

While poking at this, I noticed that the get/set config methods
on the termwiztermtab overlay weren't hooked up, and also made
a point of calling those for any overlays during a window config
reload event, so that per-window overrides are more likely to get
picked up and respected.

49ab340a92 debug overlay: remember last log line globally
It can be confusing to see the same log lines when re-opening
the debug overlay, so this commit remembers the last line
in a global to make that feel more natural.

Because that causes the initial `OpenGL Initialized!` log to
show only in the first instance of the overlay, that log line
is now changed to debug level and the overlay will now
explicitly log the version information, along with some
brief usage text:

```

179ec9faaf wezterm.mux.set_active_workspace now updates the gui
Attach the mux events to the frontend workspace reconciliation function
so that the window is updated to match the new workspace.

Ensure that we correctly clear out any overlay panes as part of the
switch: we need to remove them from the mux so that the mux will
correctly identify that the mux is empty when the main panes from
the workspace are closed.  The problem case was that the debug overlay
state was forgotten by the gui when activating the new workspace, but
we didn't tell the mux to kill it off, so subsequently CTRL-D'ing
the windows closed the windows but left the wezterm process running with
no head.

d78cc6edb8 new: exec_domains
An ExecDomain is a variation on WslDomain with the key difference
being that you can control how to map the command that would be
executed.

The idea is that the user can define eg: a domain for a docker
container, or a domain that chooses to run every command in its
own cgroup.

The example below shows a really crappy implementation as a
demonstration:

```
local wezterm = require 'wezterm'

return {
  exec_domains = {
    -- Commands executed in the woot domain have "WOOT" echoed
    -- first and are then run via bash.
    -- `cmd` is a SpawnCommand
    wezterm.exec_domain("woot", function(cmd)
      if cmd.args then
        cmd.args = {
          "bash",
          "-c",
          "echo WOOT && " .. wezterm.shell_join_args(cmd.args)
        }
      end
      -- you must return the SpawnCommand that will be run
      return cmd
    end),
  },
  default_domain = "woot",
}
```

This commit unfortunately does more than should go into a single
commit, but I'm a bit too lazy to wrangle splitting it up.

* Reverts the nil/null stuff from #2177 and makes the
  `ExtendSelectionToMouseCursor` parameter mandatory to dodge
  a whole load of urgh around nil in table values. That is
  necessary because SpawnCommand uses optional fields and the
  userdata proxy was making that a PITA.
* Adds some shell quoting helper functions
* Adds ExecDomain itself, which is really just a way to
  to run a callback to fixup the command that will be run.
  That command is converted to a SpawnCommand for the callback
  to process in lua and return an adjusted version of it,
  then converted back to a command builder for execution.

My conclusion is that either something in MESA/EGL or the IME is
generating calls that we cannot see into and that one of those is
referencing the window id that we just destroyed.

The resolution then is a bit gross: instead of destroying the window
when we need to close it, we first unmap it to remove it from the
screen, then after 2 seconds we destroy it.

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.

1b766326fd debug overlay: now supports statements as well as expressions
Previously, trying to do something like `foo = "bar"` in the debug
overlay wouldn't succeed, because we were always trying to wrap
the line inside `return {line}`, which allowed for only expressions
to be used.

Now we also allow a fully formed statement to be used, which means
that that kind of assignment can be performed in the repl, making
it a bit more convenient to try stuff out.

Using the newly exposed-to-lua mux apis, you may now run some lua code
at GUI startup and/or mux startup, just prior to any default windows
being created.

If you happen to spawn any panes as a result of this, wezterm will
skip creating the default program.

```lua
local wezterm = require 'wezterm'
local mux = wezterm.mux

-- This produces a window split horizontally into three equal parts
wezterm.on("gui-startup", function()
  wezterm.log_info("doing gui startup")
  local tab, pane, window = mux.spawn_window{}
  mux.split_pane(pane, {size=0.3})
  mux.split_pane(pane, {size=0.5})
end)

wezterm.on("mux-startup", function()
  wezterm.log_info("doing mux startup")
  local tab, pane, window = mux.spawn_window{}
  mux.split_pane(pane, {size=0.5, direction="Top"})

e8bb0e03ee add wezterm.mux lua module
The intent is to expose Mux related functions to lua, so `wezterm.mux`
will be that module table.

In order to test this out in the debug overlay, I realized that the
overlay was running functions in a different thread and didn't have
access to the mux, so this commit also tweaks the debug overlay repl to
execute the input in the main thread.

The result is that it is now possible to do
`wezterm.mux.active_workspace()` in the debug overlay to print the
active workspace name.

More functions will follow.

5bf736bd21 add PaneSelect key assignment
This is still a bit of a WIP, but this commit:

* Introduces a new "Modal" concept to the GUI layer. The intent is
  that modal intercepts key and mouse events while active, and renders
  over the top of the rest of the normal display.
  I think there might be a couple of cases where key events skirt
  through this, but this is good enough as a first step.
  Also, the render is forced into layer 1 which has some funny side
  effects: if the modal choses to render transparent, it will poke
  a hole in the window because all the rendering happens together:
  there aren't distinct layer compositing passes.

* Add a new PaneSelect action that is implemented as a modal.
  It uses quickselect style alphabet -> pane label generation and
  renders the labels over ~the middle of each pane using an
  enlarged version of the window frame font.  Typing the label
  will activate that pane.  Escape will cancel the modal.

More styling and docs will follow in a later commit.

da7da888cd config: generate errors for things like --config tarm=foo
Invalid option names, or values that evaluate as nil (such as the `foo`
above: that's treated as a global variable reference, but `foo` isn't a
defined global and evaluates as `nil`) will now cause the program
startup to error out with an actionable error message.

Previously, the invalid config name would generate a warning, and the
invalid value would silently have no effect as it has the same effect as
omitting the named value and leaving it as its default value.

I think these cases should both immediately error out and stop
further processing, so that's what we're doing.

This commit also adds support for adding:

```
   #[dynamic(deprecated = "use newer option instead")]

7858f652fb input: fix ALT when used for the leader key
The issue here was that we'd try to match this:

```
key_event RawKeyEvent { key: Char('t'), modifiers: ALT | LEFT_ALT, phys_code: Some(T), raw_code: 17, repeat_count: 1, key_is_down: true, handled: Handled(false) }
```

which has mods=`ALT|LEFT_ALT` against `ALT` and would fail.

We need to strip out the positional ALTs from the modifiers
in order to successfully match.

89e427bd79 overlays: improve key_table handling
This commit re-arranges the code so that an overlay can have a local
stack of key table activations; this allows copy_mode and search_mode
key tables to layer on top of the user's window level key tables.

Previously, we'd just stick the search_mode entry on top of the global
state, which worked, but had the undesirable side effect of hijacking
the Enter key when switching to another tab in the window.

2710cefb3e merge copy and search overlay code
The copy overlay now has a notion of running in search mode vs. copy
mode; it can be launched in either mode.

Search mode has a separate key table called `search_mode`.

Activating copy mode while search mode is active will now update
the mode of the existing overlay, rather than cancelling and creating
a new instance, and vice versa.

Activating copy mode while search mode is active will replace the
current key table activation (which is assumed to be `copy_mode`)
with `search_mode`, and vice versa.

The viewport is no longer scrolled to the bottom when activating search
mode.

Moves the key handling in the copy overlay to be driven entirely

Note: copy mode wants you to use the `Copy` assignment to actually

b375886073 mux: spawn pane if needed when using launcher to attach
If we had previously killed all the panes in a remote mux,
and then reconnected to it using the launcher menu attach option,
we could end up in a confusing state where we connect but don't
show anything for the remote; it looks like nothing happened
even though it is legitimately showing the empty remote mux.

This commit checks for that case and spawns the default program

03d8f10d11 mux: pass current window_id to Domain::attach
This commit allows the currently active window to:

* Spawn a new tab in the active window (rather than spawning
  a new window) to host the connection status
* Auto-close that connection UI tab (rather than the whole window)
  when the window is no longer needed
* Pass the current window through to use as the primary window when
  assigning remote window/tabs.

The net effect of this is that there are fewer transient windows,
and that it is easier to connect a set of domains to the active
workspace.

b908e2dd8c mux: fix update issue
The heart of the issue here was due to the window-reuse logic that
tries to reuse a GUI window that is no longer associated with a mux
window.

Each GUI window subscribes to the mux for mux events, but it filters
according to is understanding of the mux_window_id that it is associated
with.

The GUI frontend maintains an mapping of GUI and mux window so that it
knows when to reuse a GUI window and when to close it.

When connecting to a remote mux, wezterm spawns a temporary connection
progress window.  Once connected, workspace reconiliation is triggered
and decides that this window can be used for something else.

As part of workspace reconciliation, this mapping can be adjusted and
the frontend will notify a GUI window that its mux window has changed.

However, that updated mux window was not visible to the mux notification
subscription so the effect was that a variety of notifications were
effectively ignored, including updates from a remote mux when the output
was changed.

To make matters worse, the workspace reconciliation could "double-tap"
window creation and create excess windows only to later realize they
weren't needed and close them out again.

This commit addresses both of these concerns.

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.

a7cdd46720 logging: use our own custom logger
I wanted to use the Target::Pipe feature of env_logger so that we could
log to a log file as well as stderr, but it just doesn't work
(https://github.com/env-logger-rs/env_logger/issues/208).

Since we were already composing over the top of the logger in order
to capture data for our ringlog, this commit embraces that and makes
our logger responsible for both stderr and log file printing.

Thankfully, we can use the filter parsing code from env_logger to
avoid having to get too crazy with this.

Logs are stored in the runtime directory and look something like:

/run/user/1000/wezterm/wezterm-gui-log-596324.txt

Logs are collected on all platforms.

There isn't currently a thing to clean up logs.

526cc26b1e allow disabling aa for custom block glyphs
This is definitely in the band-aid category, but two issues have
mentioned the AA in custom block glyphs recently.

This commit adds an `anti_alias_custom_block_glyphs` option that can be
set to false to prevent the custom block glyphs from enabling AA.

I think a better long term fix would be some kind of hinting to avoid
the degenerate AA case, but when I made an enquiry about this class of
issue in tiny skia in the past, the author didn't want to diverge from
skia-compatible behavior, so I think we'd need to find (or build!) an
alternative rasterizer for these path instructions.

54d503de9d keys: add ActivateKeyTable assignment
`ActivateKeyTable` pushes a new named key table entry onto the stack.

It has some parameters:

* name - required; the name of a entry in `key_tables` that should be
  activated.
* timeout_milliseconds - how long the entry should remain active.
  When this duration elapses, the entry will pop itself from the
  stack. If omitted, the entry will not pop itself due to time.
* one_shot - if true (or omitted; true is default), the entry will pop
  itself after one use.  If false the entry will not pop itself after use.
  But note that if timeout_milliseconds is set then it may pop itself
  due to time.
* replace_current - if true, will pop the current stack entry before
  activating the current entry. Most useful when combined with some
  other one_shot=false activation.

`PopKeyTable` explicitly pops the top of the key table stack.
Most useful with `one_shot=false` activations.

`ClearKeyTableStack` clears the key table stack. Most useful with
`one_shot=false` activations.

```
local wezterm = require 'wezterm';

wezterm.on("update-right-status", function(window, pane)

14323a08d1 fonts: adjust descender for scaled fallback fonts
The gist of the issue is that when setting eg: scale=1.2 to draw

makes it more likely to leave the top of the cell.

This commit adjusts the y position by the difference between the
original and the scaled descender so that is less likely to cause

For the mux server, instead of being associated with a GUI window, the
clipboard was a special RemoteClipboard that would send a PDU through
to the client that spawned the window.

The bug here was that when that client went away, the clipboard for
that window was broken.

If the mux server was the built-in mux in a gui process this could
leave a tab without working OSC 52 clipboard support.

This commit restructures things so that the Mux is responsible for
assigning a clipboard handler that rephrases the clipboard event
as a MuxNotification.

Both the GUI frontend and the mux server dispatcher already listen
for mux notifications and translate those events into appropriate
operations on the system clipboard or Pdus to send to the client(s).

34090580a0 tabbar: default to a dummy, non-empty state

808d7df8d4 gui: fixup tab bar height issue
In https://github.com/wez/wezterm/pull/1779#issuecomment-1082058134 we
discuss a weird case where the tab bar height is computed as 0 and then
gets stuck at 0.

What's happening is that the initial `TabBarState::default()` value has
no items yet, and `build_fancy_tab` generates an area that occupies 0
pixels.  This computed element is cached, and then the height from that
is cached.

When `invalidate_fancy_tab` is called, it didn't invalidate the cached
height and the resultant metrics were wonky.

One possible fix for this was to also invalidate the cached height,
but since that height is already stored in the built fancy tab,
we can remove that derived-cached value in favor of just passing
down the value.

4e343eb1e5 macos: try to avoid the notch
Flesh out the get_os_parameters impl for macOS.  When running on a
system that provides `NSScreen::safeAreaInsets`, use that to determine
the border required to avoid the "notch" on certain models of mac.

In the GUI layer: when the os parameters include a border, adjust
the render position to account for it.

This is a bit of a speculative change, as I don't have a mac with
a notch.

8cb74c62d2 allow setting selection colors with alpha values
This commit allows the following configuration:

```
wezterm -n --config 'colors = { selection_fg = "clear", selection_bg = "rgba:50% 50% 50% 50%" }'
```

which sets the selection_bg to fully transparent, and selection_bg to
50% transparent gray.

When selection_fg is fully transparent we'll use the normal fg color.

When selection_bg is partially (or fully!) transparent, it will be
alpha blended over the current cell background color.

To support this, the config file will now accept rgba colors specified
as 4 whitespace delimited numeric values. If a value ends with `%` it
is interpreted as a number in the range 0-100.  Otherwise, it is
interpreted as a number in the range 0-255.  The 4 values are
red, green, blue, alpha.

At this time, only the selection_fg and selection_bg settings accept
alpha values.

bd47979292 revise ligature render / cursor intersection
This puts to final rest #478, wherein ligatured glyphs that span
cells would render portions of the glyph with the wrong fg color,
where wrong was usually the bg color and cause the glyph to turn
invisible when cursoring through the ligature.

The approach used here is to divide the glyph into 7 discrete strips
where each strip either intersects with the cursor, the selection, or
neither. That allows us to render each strip with the appropriate
foreground color.

This change simplifies some of the logic and allows some other code
to be removed, so that feels good!

As is tradition with these renderer changes, there's a good chance that
I overlooked something in testing and that the metrics or alignment
might be slightly off for some font/text combo.  Let's see how this
goes!

1e32ccbd2f shaping: fix an issue where we'd lose combining marks like U+20d7
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).

9de0e1ac90 shaping: improve glyph cell width math
This is a more robust approach; we make a separate pass to figure
out information about the (harfbuzz) cluster for a sequence of glyphs,
and then map that sequence back to the original cell sequence, and
from there compute the total cell width for the run, then distribute
the glyphs across the run.

This should yield more sane results for bidi.

98f35bbf24 bidi: tag Line with bidi mode
This commit refines bidi property handling:

* experimental_bidi has been split into two new configuration settings;
  `bidi_enabled` (which controls whether the terminal performs implicit
  bidi processing) and `bidi_direction` which specifies the base
  direction and whether auto detection is enabled.
* The `Line` type can now store those bidi properties (they are actually
  split across 3 bits representing enabled, auto-detection and
  direction)
* The terminal now has a concept of active bidi properties and default
  bidi properties
* The default properties are pulled from the wezterm configuration
* active bidi properties are potentially set via escape sequences,
  BDSM (which sets bidi_enabled) and SCP (which sets bidi_direction).
  We don't support the 2501 temporary dec private mode suggested by
  the BIDI recommendation doc at this time.
* When creating new `Line`'s or clearing from the start of a `Line`, the
  effective bidi properties are computed (from the active props,
  falling back to default propr) and applied to the `Line`.
* When rendering the line, we now look at its bidi properties instead
  of just the global config.

The default bidi properties are `bidi_enabled: false` and
`bidi_direction: LeftToRight` which corresponds to the typical
bidi-unaware mode of most terminals.

It is possible to live reload the config to change the effective
defaults, but note that they apply, by design, to new lines being
processed through the terminal.  That means existing output is
left unaffected by a config reload, but subsequently printed lines
will respect it.  Pressing CTRL-L or otherwise contriving to have
the running application refresh its display should cause the
refreshed display to update and apply the new bidi mode.

0324ff66f0 wezterm: add experimental_bidi config option and very basic bidi
This commit is larger than it appears to due fanout from threading
through bidi parameters.  The main changes are:

* When clustering cells, add an additional phase to resolve embedding
  levels and further sub-divide a cluster based on the resolved bidi
  runs; this is where we get the direction for a run and this needs
  to be passed through to the shaper.
* When doing bidi, the forced cluster boundary hack that we use to
  de-ligature when cursoring through text needs to be disabled,
  otherwise the cursor appears to push/rotate the text in that
  cluster when moving through it! We'll need to find a different
  way to handle shading the cursor that eliminates the original
  cursor/ligature/black issue.
* In the shaper, the logic for coalescing unresolved runs for font
  fallback assumed LTR and needed to be adjusted to cluster RTL.
  That meant also computing a little index of codepoint lengths.
* Added `experimental_bidi` boolean option that defaults to false.
  When enabled, it activates the bidi processing phase in clustering
  with a strong hint that the paragraph is LTR.

This implementation is incomplete and/or wrong for a number of cases:

* The config option should probably allow specifying the paragraph
  direction hint to use by default.
* https://terminal-wg.pages.freedesktop.org/bidi/recommendation/paragraphs.html
  recommends that bidi be applied to logical lines, not physical
  lines (or really: ranges within physical lines) that we're doing
  at the moment
* The paragraph direction hint should be overridden by cell attributes
  and other escapes; see 85a6b178cf

and probably others.

However, as of this commit, if you `experimental_bidi=true` then

```
echo This is RTL -> عربي فارسی bidi
```

(that text was sourced from:
https://github.com/microsoft/terminal/issues/538#issuecomment-677017322)

then wezterm will display the text in the same order as the text
renders in Chrome for that github comment.

a590955229 spawning a new tab didn't unfocus current pane
This commit centralizes the focus-loss logic to the Window so
that activating a new tab will deactivate the pane in the current
window.

Note that this cannot see overlays in the gui, but overlays shouldn't
care about focus, so it should be ok.

d169088694 fix clipping issue in fancy tab bar
We budget size based on the x_advance, which can be 1 pixel less
than the width of the glyph texture, so we could often end up
omitting the last character in "Launcher" or "default" in the
tab title or right status area.

This commit uses x_advance in both places.

b6141d650e launcher: improve scrolling through options and mouse selection
Make the scrolling mostly independent of the active row; adjust

Mouse movement no longer changes the scroll position.  Instead,
the wheel is used to scroll the list.

39c2da3bdf avoid race condition when closing last window in a workspace
This isn't ideal, but it is better than previously: we would
close the window and before the Drop impl had updated the
list of known windows, we'd try to re-assign that window
to another mux window in a different workspace, but it would
never appear because the window was closed.

6d288696c8 Add SwitchToWorkspace keyassignment action
This action causes the active workspace for the gui to change.

If the name is omitted a random name will be generated.
If the workspace doesn't exist, it will be be created.
The optional spawn parameter can be used to launch a specific
program into the new workspace; if omitted, the default prog
will be used.

The gui only supports a single active workspace. Switching workspaces
will repurpose existing gui windows and re-assign them to windows
in the new workspace, adjusting their size to fit those windows,
spawning new windows or closing unused windows as required.

The gui now exits when there are no panes in the active workspace,
rather than no panes at all.

9a241509a4 mux: add current identity concept
The mux now has a notion of which client is actively doing things.
This allows, for example, newly spawned windows to take on the
active workspace for a given client.

The gui now assigns a client id on startup, and sets the active
workspace to `default`.

The mux server temporarily overrides the active id to that of
the currently dispatching client when processing PDUs.
