579da93ded Support GNUReadline-style Alt-Backspace
Alt-Backspace is the GNUReadline-style shortcut for kill-previous-word.
In wezterm, this currently doesn't work, since this gets trapped by the generic `Backspace` match case.
This diff adds a more specific case for when Backspace is combined with Alt to produce the correct sequence.

This is definitely a hack and there should probably be a more general solution for GNUReadline combinations, but this solves the immediate problem.

1ab438c1e2 improve emoji width calculation
I noticed while scrolling `emoji-test.txt` that some of the combined
emoji sequences rendered very poorly.  This was due to the unicode
width being reported as up to 4 in some cases.

Digging into it, I discovered that the unicode width crate uses a
standard calculation that doesn't take emoji combination sequences
into account (see https://github.com/unicode-rs/unicode-width/issues/4).

This commit takes a dep on the xi-unicode crate as a lightweight way
to gain access to emoji tables and test whether a given grapheme is
part of a combining sequence of emoji.

03f51f7be2 macos: fix alt+<ascii> key being passed to terminal
This was an unintended casualty of the recent gui layer refactoring.

If you press `option-h` macos generates DOT ABOVE which we pass through
to the terminal key processing layer.  It sees that ALT is set and emits
an escape byte (to indicate that ALT is set) followed by the UTF-8
sequence for DOT ABOVE.  `zsh` gets confused and treats this as
`<ffffffff>` in its line editor.

This diff restricts the emission of the ESC leader to ascii alphanumeric
characters only.

There needs to be a followup diff to allow configuring how we process
these ALT modified characters on macOS because our current behavior
breaks eg: `ALT-1` which is a hotkey that I use in tmux.  Granted that
I don't need tmux with end to end wezterm, but it does prevent me from
using that if I wanted to.

d80169ceff Avoid accidental application mode delete output in key processing
I thought that I'd broken something with the DEL processing in vim with
the new frontend but it turned out that the other frontend was emitting
BS always and that I'd actuall unbroken passing DEL through and that
other layers were translating DEL into an application cursor mode output
for DEL that emits a totally different sequence.

This diff preserves DEL and disables that other sequence.

Will follow up with some explicit configuration to control this
behavior, but in the short term, the default behavior should be much
closer to what people actually want and expect!

764597851c allow collapsing mouse events in the mux protocol
Repeated moves or wheel events are collapsed so that we don't clog up
the queue.  The queue size doesn't matter as much as the latency of
processing a large queue.  For fast or repeated moves the queue can grow
rather quickly, and with what is currently ~25-50 ms round trip per
entry for a remote session, that is a poor UX.

fb636995c8 separate application cursor keys
Application cursor keys are a separate set of encodings that applications can
ask the terminal to produce for cursor keys.

Unfortunately, PuTTY generates these for shift-modified cursor keys.  If an
application is to distinguish between normal and shift-modified cursor keys
on PuTTY then it will need to be able to distinguish between normal and
application cursor keys.

Add new `KeyCode` variants for application cursor keys.

acc895f1cd avoid deadlock while pasting large chunks of text
A big paste could saturate the input/output of the pty and
lead to an effective deadlock; the application wants to send
output to us but we are busy trying to write the paste to it.

Break up large pastes into chunks and send them piece by piece.
This does mean that a large bracketed paste is not an atomic
unit any longer, but it seems to work out ok when pasting into
vim.

We were incorrectly treating it as \r\n, but it should only have

49467515d6 when erasing the display ensure line size matches physical
In the case where the screen was enlarged, we don't eagerly resize
the line vectors.

If a subsequent erase display occurred, we'd only erase to the old
size of the lines, rather than the new size, which could result
in a black square in the upper right corner of the display.

Repro scenario is:

* resize window larger than initial height
* `dialog --yesno hello 0 0`

The dialog background should fill the display.

I've had mixed results with esctest; the IRM and cursor save/restore

1a883a40e9 use vte with larger OSC buffer support
I wanted to see how much work remains to enable iterm2 image
display; one of the blockers was a limit in the size of the
buffer in the vte crate, which has been removed in my fork
of vte.

As part of testing our ability to absorb that data, I found
a couple of issues with applying the image cells to the display,
so this commit also takes care of that.

We still don't have code to connect the cell image data to the
opengl render layer.

f261f079f7 lift clipboard hotkeys up to gui layer
My original idea was that I would centralize of the key binding
logic in the terminalstate, but this places a bit of a burden on
the TerminalHost portion of the interface.

In particular: when running a multiplexer server we may be headless
or have multiple heads.  In that scenario we want the terminal
to be backed by a virtualized screen, and that means removing
the direct callback to access eg: the host clipboard.  This
diff is the first of a couple that have the goal of removing
those sorts of dependencies.

d7b55382b4 big initial mux change
This is an unfortunately large diff that:

* Separates Tab ownership from TerminalWindow
* Introduces a Mux container for all of the tabs in the application,
  across all windows
* Moves ownership of processing pty responses to the mux; it sets
  up and has logic to process data for the ptys and apply to the
  tabs

I've moved the logic for processing new tab and new window hotkeys
to the TerminalWindow's themselves as we need some context to
associate the tab with the right window and to create a new window.

I think that will simplify and allow unifying more code.

9ad9360075 Update tab stops when resizing
The issue here was that we were not updating the tab stops when making
the window larger.  This had the side effect of causing the cursor to
move in unexpected ways when tabbing to the right.

4092796db3 Fix an issue where the background color rendered gray instead of black
When using the default monospace font on ubuntu (typicaly
DejaVuSansMono), the texture atlas would end up the bottom left pixel
being a shade of gray.

Since we were using (0,0) coords for whitespace cells, all whitespace
cells would appear shaded gray.

We now reserve a black pixel in the bottom left of the underline texture
and switch to that for whitespace instead.

I added Debug support to the ColorPalette while tracking this down,
and figured that I might as well keep it.

279b2018fd Render cursor and selection for resized lines
If the user enlarges the terminal we can have regions of the vertex
buffer that have colors that default to alpha channel 0.  This is
normally fine but breaks rendering of the cursor and the selection;
those attributes are out of band from the normal cell attributes,
especially for whitespace cells, so we need to handle those in
the degenerate case at the end of a line render.

Refactor the code that computes the cursor and selection colors
so that we can call it and use it in both places.
