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.

This commit extends the sgr color parser to support a wezterm
extension that I just made up:
```
printf "\e[48:4:255:0:0:60mhello\e0m"
```
The `4` is wezterm specific and denotes 4 channel color, in this case
RGBA. red is 255, green is 0, blue is 0 and alpha is 60; the values are
interpreted as u8 values.
CSI 38 (fg), 48 (bg) and 58 (underline) support this.

This doesn't really change any behavior, but adjusts the types
such that CSIs that set colors have the potential to track the
alpha channel and that can make it through to the GUI/render layer.
Just clamp it to the current physical, non-scrollback portion
of the screen.
This avoids a panic but doesn't address the screen size mismatch
in the associated issue.

There was a race condition where we could leave the tab
active index pointing to the wrong pane.
That meant that the tab information computed by the gui
layer would see no panes marked as active, and thus would
end up with no active tab.
This commit fixes that by clamping the active index to
the number of panes.

The recent work on the scrollback made it easier to constrain the
search region, so expose those parameters to the Pane::search
interface and to the mux protocol.
Use those new parameters to constrain quickselect search to
1000 rows above and below the current viewport by default, and
add a new parameter to QuickSelectArgs that allows overriding that
range.
A follow-up commit could make the search/copy overlay issue a series
of searches in chunks so that it avoids blocking the UI when
searching very large scrollback.

In order to avoid searching for "c", "ca", "cat" when typing "cat",
this commit introduces a hard-coded 350ms debounce.
refs: https://github.com/wez/wezterm/issues/1569
If you typed "cat" in the search, the chances are that wezterm
would kick off a search for "c" before you finished typing,
then "ca" and then finally "cat".
There was a race:
clear by_line highlights,
queue search for "c"
clear by_line highlights,
queue search for "ca"
clear by_line highlights,
queue search for "cat"
accumulate highlights for "c" into by_line
accumulate highlights for "ca" into by_line
accumulate highlights for "cat" into by_line
so the final result was a superposition of all of those results,
which was weird!
The fix is simple: clear by_line when we get the results of
an async search.
When adding sparse ranges the cartesian product of range combinations
was explored to find intersections, which is pretty awful if there
are 1 million entries to be inserted.
This commit employs binary search to reduce the complexity, at
the expense of requiring that the internal range array is sorted.
This reduces the resident memory by another ~10% because it avoids
keeping as many runs of whitespace.
Runtime for `time cat enwiki8.wiki` is still ~11-12s, resident: 530K

The previous commit added the option to convert the storage to
the cluster format. That saves memory as rows are moved to scrollback,
but makes scrolling back more expensive due to that conversion.
This commit adds a fast(ish) path for the common case of simply
appending text to a new line before it gets scrolled: the default
format for lines in the screen is now the cluster format and,
provided that the cursor moves from left to right as text is
emitted, can simply append to the cluster storage in-place
and avoids a conversion when the line is moved to scrollback.
This improves the throughput of `time cat enwiki8.wiki` so
that the runtime is typically around 11-12s (compared to 9-10s
before introducing cluster storage). However, this is often
a deal of variance in the measured time and I believe that
that is due to the renderer triggering conversions back to
the vec storage and introducing slowdowns from the render side.
That's what I'll investigate next.
This commit causes lines to be "compressed" (really, just translated
to the new clustered line storage variant) as they move into scrollback.
The memory savings are significant for large scrollback:
`wezterm -n --config scrollback_lines=1000000`
`time cat enwiki8.wiki`
before: ~9s, Resident: 2.1G
after: ~15s, Resident: 620K (!)
The performance impact is non-trivial, and I will dig into that
next.

Previously this would create a new String because it had to, but
with the clustered storage we may be able to simply reference the
existing string as a str reference, so allow for that.
