When rendering the IME composing text, I noticed that for the Korean
input sequence: shift+'ㅅ' followed by 'ㅏ' we'd render the 'ㅆ' (the
shifted first character) in black and the composing 'ㅏ' in white
against the cursor color, and that was very difficult to read,
especially at the default font size.
To resolve this, this commit:
* Forces clustering to break around the cursor boundary, so that
we treat the cursor position as its own separately styled cluster
* Adjusts cursor/bg rendering so that we always consider the start of
the cluster for the colors of that run. We are guaranteed that a
ligatured sequence will fit in the background area anyway.
This has the effect of "breaking" programming ligatures such as '->'
when cursoring through them, and decomposing them into their individual
'-' and '>' glyphs, which is a reasonable price to pay for being able
to see things better on screen.

When we translate a dead key, send the composed event immediately
and don't try to route the current key press via the IME.
Improve rendering when in the composing state: overlay the composing
text at the cursor position to show what the composing text would
look like, even though it hasn't been committed to the input stream
yet.

For Korean text input, pressing SHIFT and then typing in certain
keys begins a composition sequence. Our logic for when to route
via the IME got so distracted by ALT that it didn't consider SHIFT
and didn't send this sequence to the IME, so we'd fail to compose
those sequences.
While poking at this, I realized that we should treat this composition
similarly to dead keys, in that we can signal the term window to
highlight the cursor color and report that status.
There's some further work to do: the composing text should be rendered
by us. So far our IME integration assumes that the IME itself will
render over the top of our window, but for this particular input
it doesn't do that.

The same core code is used to render both the tab navigator
and the launcher. The context is specified using some flags
so that you don't get an unholy mess in both places.
The net result of this is that the tab navigator now supports
fuzzy matching.

* Allow selecting the first few rows by number
* Allow scrolling through long lists of items
* Add actions from key assignments to list

Since we now have RawKeyEvent and a sane way to indicate handling,
we don't need these any more, and it simplifies key dispatch to
remove them.

Pass down whether we are in a live resize to the gui layer, so that
we don't incorrectly assume that the scale has changed, and fight
with the window manager.
Built this on my mac: will need to fixup for windows and linux.

This commit adds a couple of helper methods that provide insight into
the state of the keyboard layer.
The intent is for users to add status information about the keyboard
state.
This commit also ensures that we schedule an update when the leader
key duration expires, and ensures that we close out the leader state
for an invalid key press.

```lua
local wezterm = require 'wezterm';
wezterm.on("update-right-status", function(window, pane)
local leader = ""
if window:leader_is_active() then
leader = "LEADER"
end
local dead = ""
if window:dead_key_active() then
dead = "DEAD"
end
window:set_right_status(leader .. " " .. dead)
end);
return {
leader = { key="a", mods="CTRL" },
colors = {
dead_key_cursor = "orange",
},
}
```
When set, the cursor will change to this color during dead key
or leader key processing.
```lua
return {
colors = {
dead_key_cursor = "orange",
},
}
```

on macos only (for now), we generate a RawKeyEvent prior to
dead key or IME composition and route it to the window to give it
a chance to handle the event.
RawKeyEvent handling is scoped only to key assignments, not generating
input for the terminal.
A raw key event can be marked as handled to prevent moving on to
performing composition and generating cooked key input.

```lua
local wezterm = require 'wezterm'
return {
debug_key_events = true,
keys = {
{key="phys:Q", action=wezterm.action{SendString="woot"}},
},
}
```
The above will send "woot" to the pane whenever the key in same
physical position as Q on an ANSI standard US keyboard is pressed.

This comes from a time where our quads were always locked to grid
positions. We don't need it any more: we can simply add the adjustments
to the quad positions that we set.
Removing it makes the vertex a bit smaller and reduces the amount
of GPU accessible memory we need to use.
I'm running down a weird thing where the main font renders weirdly
when the title font is 12 pt vs the main font 10 pt.
I thought there might have been a cache invalidation issue and
realized that we could have an A-B-A style issue with the font_ptr
stuff, so I replaced it with an incrementing id.
That didn't fix the thing I was looking at, but does feel a bit
nicer overall.
The default we use on macOS looks decent. Roboto is a similar
looking font that we can use for the other platforms.
I may make it the same on all three once I've had a chance
to compare it on a mac.
Previously, we would implicitly set it to the special SEQ_ZERO
value, but since that value always flags the row as changed,
it causes some over-invalidation issues downstream in wezterm.
This commit makes that parameter required, so that the code that
is creating a new Line always passes down the seqno from that event.

We only need to recompute when the tab content changes, or when
the window is resized, plus invalidations of the shape cache
of texture atlas filling up.
Hover events don't need to re-shape.
We can now also place the tab bar at the bottom of the screen again.
The main tab area now takes the background color from the first
cell in a formatted tab bar item as the full background color
for the whole tab area, which looks a lot nicer than just the
using that color for the minimal bounding box of the tab text.
