When the title, icon, OSC 7 and SetUserVars sequences are processed,
notify the embedding application.
The gui layer uses this to trigger a titlebar update.

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.

* Make alphabet and patterns configurable
* add docs
* Enhance scrollback search to support regex captures so that
searching for eg: `fo(o)` will select the last `o` in `foo`.

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.

I've built this on linux, which doesn't respect the timeout.
I've made speculative changes that should build on mac and windows,
but that don't plumb the timeout functionality on those systems
as of yet.

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.

This commit allows the x11 window implementation to detect changes
in the DPI that occur after a window is created.
These can occur when changing desktop resolution or when changing
the accessibility option for "Large Text" in gnome.
In order to avoid continually polling for the value on every resize,
we look for the `_GTK_EDGE_CONSTRAINTS` atom in our property change
notifications. This seems to be sent at least as often as the
dpi/scaling changes.
It's also worth noting that some dpi changes don't generate resize
events, so we can't just read the dpi value on every resize, because
we'd miss some of those changes.
Part of this commit changes the font scaling logic: previously
we'd keep a notion of "dpi scale" to apply. That dates from an
earlier time in wezterm where we didn't think that we knew an
actual dpi value.
The way that worked was that we'd compare our current guestimate
of the DPI against what we though the baseline OS dpi should be to
produce a scaling factor.
On X11 that dpi value is global and we'd effectively always produce
a revised scaling factor of 1 after we'd set up the initial window.
This commit changes that logic to just pass down the actual DPI value
to the font code. That DPI value already accounts for HiDPI scaling
so this is hopefully a NOP change for the other systems.

This was broken by b441be3ac9
For whatever reason, the breakage was only visible with the Iosveka
font on Windows. I couldn't reproduce it on my other systems, even
though the code technically applies to any system.
The breakage was: the metrics resulted in a difference of about 0.4
pixels being used for the descender with that particular font, resulting
in weird vertical alignment problems.
The offset needs to be computed against the ceil of the cell height,
which removes the fractional offset.

The repro scenario for this case was:
* open GNU nano
* hit enter twice
* type hello
* move the text cursor to the top line
* double click on hello
* hit enter
Prior to this commit, the selection would remain on the now-blank line
that previously held `hello`.

This has been a commonly requested feature in the past week,
and it's a reasonable one. The mux server inherited the
close-when-done behavior from when it used to be an alternate
front-end in the same executable as the gui, but it doesn't
need to be that way any more.
We also need to accomodate that case in the client: if the
newly attached domain doesn't result in any panes being imported,
we need to spawn a new command there in order to keep the client
alive. The pre-existing check for whether the mux was empty had
false positives because the local mux may still reference the
pane from the connection UI, which would finish closing out shortly
after we had decided not to spawn anything, and then the client
would close.
