This adjusts the cursor position after emitting a sixel.
@dankamongmen: I don't have much of a sixel test suite to speak
of (cat snake.six :-p); I'd appreciate it if you could run
notcurses against this and confirm that it is doing something
sane!
At the very least, we shouldn't be warning about the unhandled
mode any more!

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.

Use a similar hsv transformation to that used to dim inactive panes
instead of the treatment that made the black look grey, which felt
like a flash instead of a dim.
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.

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.

This has the effect of reducing the memory and scroll cost
for lines that are shorter than the physical width of the
terminal matrix.

It is only used by applications that repaint on a resize event,
and us rewrapping makes it harder to have an ideal view afterwards.
This change makes us more consistent with VTE's behavior in this case.
This helps with https://github.com/wez/wezterm/issues/574 but doesn't
completely resolve it.
I didn't realize that xterm inherited some additional mappings from
the X server, so this commit should make us more comformant with
xterms behavior.
Verified this by comparing `showkey -a` under both xterm and wezterm:
```
wezterm -n --config disable_default_key_bindings=true --config debug_key_events=true start -- showkey -a
```

I've been meaning to do this for a while; this commit moves
the escape sequence parsing into the thread that reads the
pty output which achieves two goals:
* Large escape sequences (eg: image protocols) that span multiple
4k buffers can be processed without ping-ponging between the
reader thread and the main gui thread
* That parsing can happen in the reader thread, keeping the gui
thread more responsive.
These changes free up the CPU during intensive operations such
as timg video playback.
This is a slight layering violation, in that this processing
really belongs to local pane (or any pane that embeds Terminal),
rather than generically at the Mux layer, but it's not any
worse a violation than `advance_bytes` already was.

The default downscaling provided by the GPU can result in noisy
artifacts on highly detailed images.
This commit employs a cubic Catmull-Rom sampling filter for the
case where we have a single frame image that is being reduced
in size. This isn't the highest quality filter but strikes
a good balance with speed vs appearance and is strictly better
than the GPU texture sampling options that I could try.
when the size is set to auto, we'd essentially take the image as-is
and overflow the terminal.
This commit makes auto scale down the image to fit the terminal dimensions
if it is too big.
Using a boxed slice means that we hold exactly the memory required
for the file data, rather than the next-power-of-two, which can
be wasteful when a large number of images are being sent to
the terminal.
This is a API breaking change for termwiz, so bump its version.

```
echo -e "\033]777;notify;This is the notification title;This is the notification text\a"
```
Now pops up a notification in a similar manner to OSC 9, except
that this form allows setting both the title and the body separately.

Pasting a lot of text could cause a deadlock between writing
to the input side of the pty and consuming the output side.
Making the writer/input side non-blocking resolves this.
* Add ClearBuffer action
Clears all lines, both visible and those scrolled off the top of the viewport, making the prompt line the new first line and resetting the scrollbar thumb to the full height of the window.
This is the behavior that Hyper / xterm has for clearing the terminal.
* Combine ClearBuffer into ClearScrollback as enum with associated erase mode
Makes it easier to manage the different options of clearing the terminal.
This appears to have been broken since the introduction of mouse
assignments :-/
This commit adds Pane::is_alt_screen_active so that the gui layer
can tell whether the alt screen is active, and allow passing down
the event.

TL;DR: on unix, or if bracketed paste is on, then we paste with
unix newlines. If on windows && !bracketed paste then with CRLF.
See explanation in the code for more context.

These aren't currently rendered, but the parser and model now support
recognizing expanded underline sequences:
```
CSI 24 m -> No underline
CSI 4 m -> Single underline
CSI 21 m -> Double underline
CSI 60 m -> Curly underline
CSI 61 m -> Dotted underline
CSI 62 m -> Dashed underline
CSI 58 ; 2 ; R ; G ; B m -> set underline color to specified true color RGB
CSI 58 ; 5 ; I m -> set underline color to palette index I (0-255)
CSI 59 -> restore underline color to default
```
The Curly, Dotted and Dashed CSI codes are a wezterm assignment in the
SGR space. This is by no means official; I just picked some numbers
that were not used based on the xterm ctrl sequences.
The color assignment codes 58 and 59 are prior art from Kitty.

Following on from 8649056ac0,
this commit should make it harder to make a similar mistake
in the future, by introducing a new TerminalSize struct for
that purpose.
Tidies up the plumbing around pixel dimensions so that ImageData
can be rendered via the termwiztermtab bits.
I put this together to play with sticking the wezterm logo in
the close confirmation dialogs. I didn't end up using that though,
but have preserved the commented code for use in future hacking.
Sometimes, I'd notice that imgcat would have a weird aspect.
I stumbled across the root cause while debugging something else:
the order of the pixel width and height was flipped here.
