Previously, we'd unconditionally enable dual source blending for the
text foreground layer when rendering. That meant that if the user had
configured the fg color to include an alpha value it would get "stamped
through" the draw all the way to the background, making that whole pixel
take on that alpha value rather than allowing it to blend through the
way you might expect.
In prior releases that didn't matter, but since we now allow configuring
the fg color with alpha, and allow using escape sequences to set the fg
for a span to something with alpha, there is now a much higher chance of
something looking weird.
Dual source blending is only really needed for subpixel-aa and that
isn't enabled by default.
This commit changes the behavior to use regular alpha blending if the
main config (rather than a per-font override) hasn't set the freetype
load/render target to one that enables subpixel-aa.
That means that alpha channel values work as expected for fg color
by default.
If you want to enable subpixel-aa you need to enable it globally
and be aware that it will cause weirdness when trying to use alpha
channels for the fg text color.
The docs now also indicate this behavior.
This limitation could be removed by making text rendering significantly
more complex and I don't fancy doing that at this time.
Since the initial attach is async, we'd create the window at the
default/initial size and then never reconcile the size of the remote
tabs once they'd attached.
This commit introduces an event that allows the gui window to do that.
The action that it takes is to take the max width and height between
its current size and the size of a newly added tab and resizes to
that new size, if it changed.

Consolidate the attributes together rather than having them in separate
versioned sections so that it is a bit more readable.
Make a note about how attributes select from existing fonts rather than
apply styling effects to fonts.

This commit allows wezterm to spawn programs into the host rather
than in the container environment.
It feels weird that it is so trivial to "break out" of the container
sandbox, but I'm not complaining.
There are some unfortunate consequences:
* there is no `wezterm` installed on the host, so no ability to `wezterm
cli` to control it from other apps
* The unix domain socket is scoped inside the sandbox, so there's "no
way" for `wezterm cli` to reach inside anyway.
But: with this, it is at least usable to start a flatpak and open a
shell.

Allows the following assignment actions; I was just over-using z for
no real reason, I'm not suggesting that these are good assignments.
```
-- move the cursor backwards to the start of the current zone, or
-- to the prior zone if already at the start
{ key = 'z', mods = 'NONE', action = act.CopyMode 'MoveBackwardSemanticZone' },
-- move the cursor forwards to the start of the next zone
{ key = 'Z', mods = 'NONE', action = act.CopyMode 'MoveForwardSemanticZone' },
-- start selecting by zone: both the start point and the cursor
-- position will be expanded to the containing zone and the union
-- of those two will be used for the selection
{
key = 'z',
mods = 'CTRL',
action = act.CopyMode { SetSelectionMode = 'SemanticZone' },
},
-- like MoveBackwardSemanticZone by only considers zones of the
-- specified type
{ key = 'z', mods = 'ALT', action = act.CopyMode { MoveBackwardZoneOfType ='Output' }},
-- like MoveForwardSemanticZone by only considers zones of the
-- specified type
{ key = 'Z', mods = 'ALT', action = act.CopyMode { MoveForwardZoneOfType ='Output' }},
```

When `parse_first_as_vec` is parsing an OSC sequence (e.g.
`SetHyperlink`) that is terminated by the escaped form of ST (`ESC \`),
ensure that the ST sequence is included in the returned vector.
This is achieved by ensuring the VTParser has returned to the "ground"
state: i.e. the stored state after the `ESC` is processed is not enough
for `parse_first_as_vec` to terminate. We must also parse the `\` to
ensure that we return a complete span to the caller.
Fixes https://github.com/markbt/streampager/issues/57
Add `VTParser::is_ground`, which is true if the VTParser is in the
"ground" state, i.e. it has no stored state that will affect the
interpretation of future input characters.
This is included only in the json output mode.
Note that this does not and cannot include positioning information known
only to the GUI, as there may not be a GUI. That means that window
position, tab bar and padding data are not known and not able to be
returned via this interface.

This makes those fields usable in `wezterm cli list --format json`.
This doesn't change the ABI of the mux protocol, but prior to
this commit, those fields were always 0.

They prevented using other types of mouse events!
We don't have a good way to specify that kind of alias, so for now,
take it out and replace the examples in the docs with the more verbose
equivalents.

Adjusts how mouse events are matched so that we can now indicate whether
mouse reporting and alt-screen should be considered as part of the event
trigger criteria.

`4` is actually defined as CMYK according to ITU-T Rec. T.416:
> A parameter substring for values 38 or 48 may be divided by one or more separators (03/10) into parameter elements,
> denoted as Pe. The format of such a parameter sub-string is indicated as:
>
> Pe : P ...
>
> Each parameter element consists of zero, one or more bit combinations from 03/00 to 03/09, representing the digits
> 0 to 9. An empty parameter element represents a default value for this parameter element. Empty parameter elements at
> the end of the parameter substring need not be included.
>
> The first parameter element indicates a choice between:
>
> 0 implementation defined (only applicable for the character foreground colour)
> 1 transparent;
> 2 direct colour in RGB space;
> 3 direct colour in CMY space;
> 4 direct colour in CMYK space;
> 5 indexed colour.
