This makes the search feel more responsive.
We search from bottom to top so that we show the more recent results
first, but for the sake of efficiency when accumulating result chunks
we need to reverse the order of the results vec from how it was
previously.
Each result chunk is loosely ordered from top to bottom, so we sort
it and reverse it: results[0] is the bottom-most result.
New rows are accumulated on the end of the result array; this is
not only more efficient, but it preverses the match result number
ordering.
The next/prior functions need to be swapped to account for this change
in result order.

It was set to the first non-tab bar pixel y coordinate rather than
the line y pixel coordinate.
Move the calculation up!

There are caveats to determining this, but when we think
password entry is enabled, switch the cursor to the font-awesome
lock glyph instead of the normal cursor sprite.
fa_lock is used because it is monochrome and can thus be tinted
to the configured cursor color, and it respects blinking/easing.

The idea here is that different kinds of panes may want to expose
additional metadata to lua scripts. It would be a bit weird to add
a Pane method for each of those and plumb it all the way through
the various APIs, so just allowing a pane impl to return a dynamic
value (likely an Object) allows a bunch of flexibility.
This commit exposes the clientpane is_tardy boolean and the time
since the last data was recevied (since_last_response_ms) from
the mux client pane implementation: these are used to show the
tardiness indicator in the client pane.
Exposing this data enables the user to add that info to their
status bar if they wish.
The default behavior for charselect is to show the recent category
if you have previously used it, otherwise, show the default emotion
category.

CTRL-SHIFT-U is a new default key assignment for this new modal.
It opens up a fuzzy searchable browser that defaults to showing
emoji/emoticons. The category can by cycled through the suggested
emoji categories using CTRL-r. Unlike the system emoji palette,
wezterm includes a category for nerdfont symbols, and another
that is a list of all unicode codepoint names, so you should be
able to browse for pretty much any codepoint you can think of.
The modal also allows fuzzy searching based on:
* The official unicode name
* The github shortcode
* codepoint value in hex
so if you know the codepoint value but not the name, you can
still find a way to input what you're looking for.
Pressing Enter will copy the selected item to the clipboard
send it to the active pane, and cancel the modal. You can therefore
repeat the insert by simply pasting.
I plan to add frecency to this in a later commit: that way the
frequently/recently used selections will show in a category of
their own and make it easier to re-input them.

Tidy some things up to avoid some dead code and redundant impls.
Make it easier to select whether you want to implement the new
methods in terms of the old, or the old methods in terms of
the new in a given pane impl.
Remove the faulty cache key stuff and hang references to the cached
data directly off the underlying Line. That makes the association
between the the Line and the data O(1) plus some basic cache
invalidation checks.
Adjust the shape cache portion of this to use the same ID for the
shape, so that things that invalidate just the quads (such as cursor
movement when not composing, and selection) only need to recompute
the quads without re-shaping.
Adds Pane::for_each_logical_line_in_stable_range_mut and
Pane::with_lines_mut which allow iterating mutably over lines.
The idea is that this will allow the renderer to directly cache
data in the Line via its appdata without having to build cumbersome
external caching logic and managing cache keys.
This commit just swaps the implementation around for localpane
and sanity checks that the renderer functions.
Various overlays and the mux client don't properly implement these
yet and current warn at compile time and panic at runtime.
To follow is the logic to cache the data and make sure that it
works the way that I think before converting the other Pane
implementations.
The cache key isn't quite right, leading to some artifacts
in some cases.
I have a cunning plan, but it will take me a bit to wrap
it up, so in the meantime, disable these caches.

It didn't really belong there; it was added as a bit of a hack
to propagate screen reverse video mode.
Move that to the RenderableDims struct and remove the related
bits from Line
Similar to selection_fg, setting the cursor_fg to transparent ("none")
will use the foreground color of the text behind the cursor.

I broke this with the performance changes I pushed earlier today.
Poke a hole in caching for it as well, as it doesn't use the seqno
to track changes like the rest of the Line based data.

This doesn't mean that it renders at 1fps, just that it goes through
the simpler path of scheduling on the boundaries rather than at
animation_fps through the intermediate stages, where it would be
useless.
Introduces a heap-based quad allocator that we cache on a per-line
basis, so if a line is unchanged we simply need to copy the previously
computed set of quads for it into the gpu quad buffer.
The results are encouraging wrt. constructing those quads; the
`quad_buffer_apply` is the cost of the copy operation, compare with
`render_screen_line_opengl` which is the cost of computing the quads;
it's 300x better at the p50 and >100x better at p95 for a full-screen
updating program:
full 2880x1800 screen top:
```
STAT p50 p75 p95
Key(quad_buffer_apply) 2.26µs 5.22µs 9.60µs
Key(render_screen_line_opengl) 610.30µs 905.22µs 1.33ms
Key(gui.paint.opengl) 35.39ms 37.75ms 45.88ms
```
However, the extra buffering does increase the latency of
`gui.paint.opengl` (the overall cost of painting a frame); contrast the
above with the latency in the same scenario with the current `main`
(rather than this branch):
```
Key(gui.paint.opengl) 19.14ms 21.10ms 28.18ms
```
Note that for an idle screen this latency is ~1.5ms but that is also true
of `main`.
While the overall latency in the histogram isn't a slam dunk,
running `time cat bigfile` is ~10% faster on my mac.
I'm sure there's something that can be shaved off to get a more
convincing win.
This is really a proof of concept commit; I want to be able to pass
more structured data into the shader as uniforms and the basic
macros provided by glium make that a bit awkward.
What I came up with is a slightly more dynamic uniform builder
thingy.
I'm using this to pass in a copy of the various blinking easing
functions.
Those are incomplete and unused, but it shows that the technique works.
Use the font height as the basis for the size, rather than the width,
to avoid the buttons being too condensed.
Explicitly use the pixel height for the dimensions so that the
buttons are square.

The prior mutually exclusive behavior kept surprising people so let's
just flip this around.
This is potentially a "breaking" change for folks, but I think it is
worth it.
