This was originally intended to be swept in and dealt with as part of
adopting CSI-u (refs: https://github.com/wez/wezterm/issues/63) but the
default shift-space mapping is super irritating in vim (refs:
https://github.com/wez/wezterm/issues/126) so it got partially walked
back, but as a consequence we accidentally dropped the modifiers from
those keys (refs: https://github.com/wez/wezterm/issues/213 refs:
https://github.com/wez/wezterm/issues/214).
This commit restores the modifiers for that case.
In addition, since we now have a way to plumb configuration directly
into the term crate, this adds a config option to enable CSI-u for those
that want to use it.
If the image is smaller than the cell size we could end up
rounding that dimension to zero and ultimately not render
the texture to the cell.
This commit adjusts the math to round up, which yields
better results for the test in refs: https://github.com/wez/wezterm/issues/211
I noticed that we still weren't quite right.
I think the net change is really just that we must force
the use of the CSI representation when using CTRL/SHIFT
modifiers.

We were treating DECCKM as the sole thing to enable application
cursor reporting, but looking closely at the docs, that mode only
takes effect when both DECANM (Vt52 emulation mode) AND DECKPAM
(application keypad mode) are both active.
neovim enables DECCKM and DECKPAM but not DECANM.

Bound to CMD-K and CTRL+SHIFT-K by default. This also functions
while the output is filling up (eg: `find /` and hit the key binding
to keep pruning the scrollback).

The click/movement related events are now "table driven" with
defaults contained in the InputMap object.
This gives the the potential to be configured from the config
file, but there is not glue in the config layer to enable
this yet.
This also does not include mouse wheel events.
neovim will try to force the window to resize after suspend/resume.
No other terminal allows this today, so rather than log it as an
unhandled event, explicitly ignore it.
This was a bit of a pain to track down because this behavior
isn't specified anywhere or called out explicitly.
The issue is that if you use a true color escape sequence such as
```bash
printf "\x1b[38;2;255;100;0mTRUECOLOR\n"
```
the active color would remain active when switching between the
primary and the alt screen until something (eg: `ls --color`) changed
it again.
I hadn't run into this because in my prompt, many many years ago, I had
it set to perform an SGR reset (`\x1b[0m`) as the first thing to ensure
that the shell is in a saner state.
For users that don't do this they end up with a weird looking color
bleed effect.

The predictive echo feels pretty reasonable, but if the connection
is having problems and we're showing the tardiness indicator, the
echo can give the impression that your input is going to get processed.
That may not be (usually is not!) the case.
This commit makes it a bit more visually distinctive that something
isn't right by greying out the color palette in that case.

Matching against the current dir when it includes a host and a
path seems like a handy way to automate selecting appropriate
theme/color/profile settings, so I'd like to make sure that
we have the full URL content available for that.

The rewrap logic makes dealing with the cursor position a bit
more complex and we had a problem where resizing the window shorter
and then taller would allow the shell to cursor up into the scrollback
when displaying its prompt, and allow it to overwrite something that
was logically in the scrollback.
Avoids accidentally moving the y position of the cursor; previously
we would keep it pinned to the physical viewport relative coordinate,
but we didn't account for the implicit scroll that happens when
making the window smaller, which meant that the shell would re-render
its prompt with some artifacts during a resize.
Adds logic to resize handling that will consider the original logical
line length when the width of the terminal is changed.
The intent is that this will cause the text to be re-flowed as if it had
been printed into the terminal at the new width. Lines that were
wrapped due to hittin the margin will be un-wrapped and made into a
single logical line, and then split into chunks of the new width.
This can cause new lines to be generated in the scrollback when
making the terminal narrower. To avoid losing the top of the buffer
in that case, the rewrapping logic will prune blank lines off the
bottom.
This is a pretty simplistic brute force algorithm: each of the lines
will be visited and split, and for large scrollback buffers this could
be relatively costly with a busy live resize. We don't have much choice
in the current implementation.

Still not perfect; there's a window invalidation missing from
the mux somewhere on higher latency connections that gets
resolved just by moving the mouse :-/
We would leave a copy of the alt screen lines at the top of the
scrollback.
This commit ensures that those lines are marked dirty and that
the dirty bits are propagated to the client to invalidate its cache.
Use StableRowIndex to implement tracking the viewport in the gui layer.
This resolves an issue where a busy terminal would continue to scroll
through the scrollback when you were paging backwards and look weird.
There's still some cleanup though:
- This breaks the selection ui
- the cursor position is wrong when scrolling back
- shift-pageup/pagedown need to be processed in the gui layer
