This makes it possible to configure wezterm to eg: triple click
on command input (or output) to select the entire input or output
without messing around trying to find the bounds.
The docs have an example of how to configure this; it requires
setting up shell integration to define the appropriate semantic
zones.
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 revises the opacity configuration to make it more
consistently applied.
* `window_background_opacity` controls the overall window capacity,
whether a background image is present or not.
* When a background image is present, or if the window is transparent,
then text whose background color is the default background is
changed to have a fully transparent background.
* `text_background_opacity` controls the alpha channel value for
text whose background color is NOT the default background.
It defaults to 1.0 (fully opaque), but can be set to be
transparent by setting it to a number between 0.0 and 1.0.
* The inactive pane hue, saturation, brightness multipliers
have been factored out into their own struct which changes
that set of options to:
```lua
return {
inactive_pane_hsb = {
hue = 1.0,
saturation = 1.0,
brightness = 1.0,
},
}
```
* `window_background_image_hsb` is a new option that can apply
a hue, saturation, brightness transformation to a background
image. This is primarily useful to make a background image
darker:
```lua
return {
window_background_image = "/some/pic.png",
window_background_image_hsb = {
brightness = 0.3,
},
}
```

This includes a script to generate a screenshot from a wezterm
running the default config under X11.
It expects the iTerm2-Color-Schemes to be checked out alongside
the wezterm repo as it uses the dynamic color schemes scripts
to activate the schemes one by one and capture the display.
`wezterm.action{ExtendSelectionToMouseCursor=nil}` doesn't produce an
`ExtendSelectionToMouseCursor(None)` value because a table value of
`nil` is equivalent to that key not being present and lua sees just
an empty table.
Instead we need to accept `ExtendSelectionToMouseCursor={}` a valid
way to indicate an `Option::None` which is what this commit does.
Due to weirdness that I haven't had a chance to run down, passing
that value through `wezterm.action` doesn't produce the intended
value, so I'm adjusting the docs to show to specify an alternative
syntax for this as part of this commit.

This adds an extra level of indirection to the Mux model;
previously we allowed for Windows to contain an ordered
collection of Tabs, where each Tab represented some kind
of pty.
This change effectively renames the existing Tab trait to Pane
and introduces a new Tab container, so the new model is that
a Window contains an ordered collection of Tabs, and each Tab
can have a single optional Pane.

This allows setting up shortcuts relative to the final tab in
a window, rather than always being relative to the first.
The default assignment for CTRL+SHIFT+9 is now `ActivateTab=-1`
as a convenient way to always reach the last tab.
