This is to handle situations such as some versions of the Terminus
bitmap font, where the individual bitmap strike sizes are broken
out across multiple individual files.
Font matching now passes down the nominal pixel height based on
the current DPI and font scale factor, and will use that to select
the font file that has the closest pixel size.
Previously, it would be potentially undefined which of the Terminus
font files would be selected.

This font is a bit funky; the bitmap strikes are only 4px wide:
```
; ftdump gohufont.otb
There is 1 face in this file.

but using that the cell size isn't right.
We draw from the metrics we compute via cell_metrics to get more
information; we don't get a valid height from that (just 0!), but
we do get the much more plausible width of 8 pixels.
So we take the max of the two techniques for figuring the metrics.
That appears to work out, and also doesn't appear to break emoji
fonts.

This commit adjusts the the window event routing/queuing so that
a queued event can capture a pane_id other than the focused pane.
Since we only allow one queued instance of a given named event in a
window, a consequence of this is that multiple bell events coming
from different panes at the same time may race and the loser's
event will be dropped. We log a warning in that case.

This was a bit of a PITA to run down; the essence of the problem
was that the shaper was returning an x_advance of 0 for U+3000,
which caused wezterm's shaping layer to elide that glyph.
I eventually tracked down the x_advance to be the result of
scaling by an x_scale of 0, which in turn is the result of
harfbuzz not knowing the font size.
The critical portion of this diff is the line that advises
harfbuzz that the font has changed after we've applied the
font size.
The rest is just stuff to make it easier to debug and verify.
This:
```
printf "x\u3000x."
```
Now correctly renders on screen as "x x".

This commit introduces a mechanism for specifying resize increments
for a window, and then arranges for the termwindow to set those
to match the current font cell metrics.
This should help to avoid cases where there is excess padding pixels
resulting from the window being slightly larger than computed number
of cells and the font metrics.
It appears as though kakoune hides the terminal cursor and renders
its own version of the cursor.
The hidden state was being picked up by the copymode overlay,
making it awkward to use.
This commit forces the cursor to be visible (and a block) when
copy mode is active.

Not sure what happened here: presumably a borked merge or something
similar, but this commit allows `window:get_appearance` to return
the actual appearance value on X11.
Even though this plumbs the call through to Wayland, Wayland doesn't
provide an equivalent concept so still always return Light, as is
mentioned on our docs.

This commit annotates fonts with a boolean that indicates whether
we think it contains glyphs with emoji presentation, and then
passes the cluster.presentation field down to the shaper.
If the presentation doesn't match the current font in the fallback,
then it will be skipped until we exhaust its options.
`wezterm ls-fonts` also shows whether we think a font has emoji
presentation.

Test scenario is:
* Create a split
* in each pane run: `printf "\e[?1004h" ; od -c`
* Focus the panes, focus another window, and focus the window again
* The I and O events appear in the panes when changing their focus.
* Previously, only the active pane would get focus events when the
window focus changed.

The man page states:
> For each parameter, the first obtained value will be used.
but then later says:
> It is possible to have multiple identity files specified in
> configuration files; all these identities will be tried in sequence.
> Multiple IdentityFile directives will add to the list of identities
> tried (this behaviour differs from that of other configuration
> directives).
So that's what this commit does
The main culprit was the calloop feature that is used by default
in the underlying SCTK crate.
This commit:
* Routes keyboard processing via the same keyboard mapping code
that we use for X11
* Implements key repeats directly, and with awareness of elapsed
time in case the repeat rate is quicker than the event dispatching
quantum
* Disables the calloop feature of SCTK and let us do our own polling
of the wayland connection.
Critically, key repeat is sticky and unpredictable while calloop is
enabled.

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.

neovim doesn't like it when multiple drag events with the same
coordinates are received; it appears to treat that as though
the mouse button was double clicked.
This commit teaches the mouse report encoding to suppress multiple
drag events in succession that have the same payload.

This looks like a honest typo from when panes were introduced!
We were passing the tab id rather than the pane id when specifying
the target of a split.

Since removing the regular periodic background tasks, we're now
prone to not noticing child processes exiting.
This commit explicictly schedules a thread to do that on Windows
so that we can close a tab as soon as it exits.
This commit adds a slant to *scalable* (not bitmap!) fonts whose
originating font attributes requested italics but for for which
the resolved face is not italic.

Two issues here:
* The hue angles need adjusting to work with the palette library
* The resultant RGB color had the wrong gamma level, resulting in
an overly bright image.

There were two bugs here:
* \u8D (the utf8 encoded representation of 0x8d, aka: RI) was not
recognized as a C1 code and was instead passed through as printable
text.
* The \u8D is a zero-width sequence which means that a subsequent
set_cell call on the new empty-by-default line wouldn't allocate
any cells in the line array, and the assigment to the line would
panic.
This commit avoids the panic for the second case, and then fixes up
the vtparser to correctly recognize the sequence as a C1 control.

Since the original code was written, Rust grew and stabilized
an interface for specifying argv0 for the child process, so
we can remove the fragile `-l` argument passing.

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.

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.
