@yoichi reports that:
```bash
printf "\x1bPqh"
```
would panic wezterm; the issue was that the maximum x value was
only being updated for newlines and that sequence didn't include it.

There were two problems:
* It was using an old code path that didn't even try to resolve the cwd
* The NewWindow code path would "forget" the originating window and then
fail to resolve the current pane + path from the new, empty window
that it is building.

Adds some supporting methods for computing the `SemanticZone`s
in the display and a key assignment that allows scrolling the
viewport to jump to the next/prev Prompt zone.
This commit allows the terminal to tag cells with their semantic
type, as defined by OSC 133 escape sequences.
The gist of it is that each cell is now semantically one of:
* Output (eg: from the activity performed by the user. This is the
default)
* Input (eg: something that the user typed as input)
* Prompt (eg: "uninteresting" chrome/UI from the shell)
The semantic type is applied almost exactly like an SGR attribute,
except that resetting SGR doesn't clear the semantic type.
Tagging the cells in this way allows for smarter UX in the future;
for example, selecting the entire input or output from the last
command without fiddling around to avoid the prompt line(s),
or "paging up" to a prior prompt rather than page.
This doc covers those escapes as used in domterm, iterm2 and other
terminals:
https://gitlab.freedesktop.org/Per_Bothner/specifications/blob/master/proposals/semantic-prompts.md
This is an example of how to configure the shell to emit these
sequences; I'll add a proper little blob of shell specifically
for wezterm in a later commit:

I've had a FIXME in here for a while to check the positioning,
but never got around to it.
The onefetch folks have an app that does care about this,
so it's time to resolve it!
This commit adjusts the cursor position for the iterm case
(not the sixel case), and results in both:
running in xterm:
```
onefetch --image ~/Downloads/squirrel.png
```
running in wezterm:
```
TERM_PROGRAM=iTerm.app onefetch --image ~/Downloads/squirrel.png --image-backend=iterm
```
```
onefetch --image ~/Downloads/squirrel.png --image-backend=sixel
```
showing consistent positioning.

This is basically the same issue as
70fc76a040 but on macOS. Now that we're
using EGL in more places, the same sort of check needs to used in more
places!
Will need to do the same on Windows in a follow-up commit.

This reverts to the original resize behavior of padding out
the display when resizing taller, but only for Windows systems.
More explanation in the comments in the code.
refs: #138
Needed to re-order a couple of things to match recent changes.
Also: don't hard fail if the ssh server rejects a setenv request,
just log the error instead.
This seems to make our resize behavior a bit nicer and more
consistent with eg: xterm.
Previously we'd consider the previously existing scrollback
as immutable and prefer to add excess blank lines of padding
when making the window taller.
In practice that meant that content would scroll back when
making the window taller, which is annoying.
This commit removes that constraint and instead will prefer
to maintain the cursor position relative to the top of the
viewport when the size changes.

Not 100% sure that this is it, but it seems much less likely that
artifacts will appear in conjunction with transparency when the window
shadow effect is disabled; I didn't see the ghosting with this disabled,
but I sometimes dididn't see it with it enabled, so I'm not sure that we
have a 100% reliable reproduction, and thus am not sure that this is a
fix.
I found mention of disabling the shadow in some example code on
stackoverflow when I was first researching this, but it wasn't supplied
with an explanation. Perhaps this is why?
Longer term we might want to be smarter about turning off the shadow
only when the opacity is != 1.0, but at the moment the window layer
can't see the config, so let's just default it off for the moment
until we see if it does the trick.

This avoids having a green (by default) border around the cursor.
The dynamic color escape sequences have been updated to also
change the border color when the cursor background color is changed.
A consequence of reducing the initial texture size is that for
larger starting font sizes it isn't big enough. We need to make
a couple of passes to determine the required size, so that's
what this commit does.
refs: #307
This commit introduces a small, bounded, LRU cache for recently
decoded images.
This allows the same image ID to be used in the cache that the
same image bits are repeatedly sent to the terminal.
This is advantageous because it reduces the amount of texture
space required by the gui layer.
I changed this to `wezterm-gui` thinking it would be a hair more
efficient, but it makes it difficult to access the cli side of
things from the appimage.
This wasn't used by anything and the version was getting pretty stale.
Upgrading is awkward because newer versions pull in an incompatible
freetype library version.
Wheel events wouldn't get reported to eg: vim in wsl if the
window's X position was larger than the window width due to
mouse wheel messages being reported with screen coordinates
rather than client coordinates.
This commit addresses that.
