I added this originally thinking that it would make it easier to resolve
https://github.com/wez/wezterm/issues/695 and to integrate wgpu support,
but it's the cause of https://github.com/wez/wezterm/issues/922 so let's
take it out and more directly connect the window events to those in the
terminal.
This commit likely breaks mac and windows; pushing it so that I can
check it out and verify on those systems.
0.8 doesn't seem to build with rusttls, but I don't think
we need that any more: we've been using vendored openssl on windows
and mac for some time.

Previously, if the config file had errors, ls-fonts would silently
continue with the default config, which was confusing.
Make a point of checking and reporting config file errors.
You can run `cargo build --release --no-default-features` to build
without wayland support.
This is useful for systems that do not have wayland (eg: the `slint`
distro).
This section of the code wasn't looking up the custom glyphs
and would always use the font. We can make rendering a little
more efficient if we skip the font resolution for this case,
and the code is much simpler if we just use our own box drawing
glyphs, so that's what we're doing here.

The issue is that the pane was only removed from the tab when explicitly
closed, leaving it to be later detected and flushed.
However, in the meantime, when performing eg: cursor blink maintenance,
if the set of panes in the tab is empty then the window would close.
The resolution is to ask the mux (rather than the tab) to kill the pane,
so that the cascading closure of the tab causes the window's active
tab to reference the correct remaining tab.

This changes the fill_rect function over to use the zeno crate.
zeno allows describing a path and filling or stroking.
This commit doesn't strictly need that, but it sets things
up for more interesting custom glyphs in later commits.

Same vein as 8931afba5cee07ab12990f06c2ff34d6f8426b19; the auth
window could sometimes get stuck until an input event was sent
to it.
Wire up a mux event so that the window can close itself.
When the client connected to an empty remote mux, it would allocate an
empty window and then spawn a new tab into it.
Meanwhile, the authentication window would close and trigger a prune of
all empty windows, causing the in-flight spawn to fail because its
destination window was removed.
This commit defers window pruning while Activity is in progress;
the MuxWindowBuilder has an associated Activity count.
in the same vein as d657721163, the
increased idle loop means we need to be careful not to suppress
invalidation events.
In this case, overlays aren't from the window in the mux model,
so we'd ignore invalidations for those.
While looking at this I realized that we'd also do the same
for output being emitted in panes that were not the active pane,
so tidy that up.
in the same vein as d657721163
this commit introduces more assertive signalling from the remote
mux when a pane is closed so that the client can update.
As part of reducing the amount of regularly scheduled stuff wezterm
does in the background, this commit restructures how an empty mux
is detected; now when the mux prunes dead windows it will emit
an Empty event.
The Activity type will now schedule a prune when it is dropped,
which will clean up and trigger the Empty event.

Adds a `ShowDebugOverlay` key assignment that will create a tab

This got a bit broken by the fix for https://github.com/wez/wezterm/issues/714
since we can be handed a range of logical line fragments, we should
test each of them to find our matching result.
Also, improve the logic for constraining the length when looking
backwards.
This commit introduces the knowledge about whether a font is
scalable or was using bitmap strikes (eg: color emoji bitmaps).
Then that information is used to help figure out whether and
how to scale a glyph.

Previously, we used `git describe --tags` to produce a version number
for non-released builds derived from the most recent tag + some info
such as the number of commits since that tag and then `g{HASH}`.
That always confuses people because the date portion at the front
looks old (it is typically the previous release) and the hash at
the end has that `g` in it.
This commit simplifies both the tag name used when making a release
and the computed version number take the date/time from the current
commit, and then append the hash. That way the version number always
corresponds to a commit.
This scheme doesn't help detect situations where the commit is
dirty, but I don't think the old one would have helped with that
either.
the binary search would falsely extend the end of the match
to the start of the subsequent match for the wrapped line case.
The resolution is to emit a coordinate for the newline that we
add to the haystack between the wrapped lines.

In the situation where we have a full screen terminal (eg: 500 cells
wide), but very little output (eg: only 10's of columns on the left are
NOT blank), we would previously spend a non-trivial amount of time
calculating fg/bg colors for the blanks that trailed the actual
clusters; the calculation for each row was:
O(trailing-blanks * full cell color compute cost)
which was around 30us per row. For large numbers of rows this could
add up to >10ms per frame.
This commit changes the logic to run in two phases:
* O(selection-width) with simple fg/bg color updates for the selection
range
* O(1) full cell color compute cost for the cursor if the cursor
is somehow in the trailing blank region and not already handled
by the earlier clustering logic.
With the sequence of recent commits, the frame time for the large
terminal case has been reduced from ~22ms to ~7ms, which is approx 3x
improvement.

It looks like the mux search results include a trailing newline
in some cases, which means that a match can wrap onto a second
line.
If that line is shorter than the label length, we could panic.
This commit makes quickselect safer to use in this situation,
but the real fix is with the mux search code.
It's not perfect; this only handles the case where you move down
into the terminal. I couldn't easily make the same thing happen
when moving the mouse up or left outside of the window. It's
probably fixable but this is better than it was.

This is the first pass implementation, drawing on the alphabet logic
and default patterns from tmux-thumbs (thanks @fcsonline!).
ctrl-shift-space pops up the quick select overlay.
Typing the highlighted prefix will select the matching text and
copy it as though the `Copy` key assignment was used.
TODOs are to make the alphabet and patterns configurable, as well
as write up some docs.

back out the portion of the cap height scaling that applied when
we knew the cap height of the primary font but not a fallback font.
That logic allowed some overly wide powerline fonts to be sized
correctly (a bit smaller), but also meant that a number of emoji
and other symbol glyphs were now undersized.

It now outputs something that you could conceivably put into
your config file, although the intent is to show the canonical
way to reference the individual fonts that were found, rather
than to specify a fully baked list to paste into a config.
eg:
```
; ./target/debug/wezterm ls-fonts
Primary font:
wezterm.font_with_fallback({
-- /home/wez/.fonts/OperatorMonoSSmLig-Medium.otf, FontDirs
{family="Operator Mono SSm Lig", weight="DemiLight"},
-- /home/wez/.fonts/OperatorMonoSSmLig-Medium.otf, FontConfig
{family="Operator Mono SSm Lig", weight="DemiLight"},
-- /home/wez/.fonts/MaterialDesignIconsDesktop.ttf, FontDirs
"Material Design Icons Desktop",
-- /home/wez/.fonts/terminus-bold.otb, FontDirs
{family="Terminus", weight="Bold"},
-- /home/wez/.fonts/JetBrainsMono-Regular.ttf, FontDirs
"JetBrains Mono",
-- /home/wez/.fonts/NotoColorEmoji.ttf, FontDirs
"Noto Color Emoji",
-- /home/wez/.fonts/MaterialDesignIconsDesktop.ttf, FontConfig
"Material Design Icons Desktop",
-- /usr/share/fonts/terminus-fonts/ter-u32n.otb, FontConfig
"Terminus",
-- /home/wez/.fonts/JetBrainsMono-Regular.ttf, FontConfig
"JetBrains Mono",
-- /home/wez/.fonts/NotoColorEmoji.ttf, FontConfig
"Noto Color Emoji",
-- <built-in>, BuiltIn
"Last Resort High-Efficiency",
})
```
we now compute the ratio of the cap height (the height of a capital
letter) vs. the em-square (which relates to our chosen point size) to
understand what proportion of the font point-size that a given font
occupies when rendered.
When rendering glyphs from secondary fonts we can use the cap height
ratios of both to scale the secondary font such that its effective
cap height matches that of the primary font.
In plainer-english: if you mix say bold, italic and regular text
style in the same line, and you have different font families for
those fonts, then they will now appear to be the same height where
previously they may have varied more noticeably.
For emoji and symbol fonts there may not be a cap-height metric
encoded in the font. We can however, improve our scaling: prior
to this commit we'd use the ratio of the cell metrics of the two
fonts to scale the icon/emoji glyph, but this could cause the glyph
to be slightly oversized as seen in https://github.com/wez/wezterm/issues/624
If we know the cap-height of the primary font then we can additionaly
apply that factor to scale the emoji to better fit the cell.
While looking at this, I noticed that the aspect ratio calculation
for when to apply to the allow_square_glyphs_to_overflow_width option
had width and height flipped :-(

This addresses the render artifacts aspect of https://github.com/wez/wezterm/issues/671
For whatever reason, some font(s) cannot be loaded on that system
and that results in the paint routine erroring out.
This commit avoids the error by substituting a blank glyph
instead of the glyph that failed to load.
