During a live resize, we could queue up a lot of `window-resized`
events, which is undesirable.
This commit introduces a simple but effective mechanism to manage this;
a given event can have at most one executing and one pending copy.
So if we get a burst of resize events (eg: during a live window resize)
that might have previously queued hundreds of discrete events, we now
get a more manageable situation with 1 executing and 1 queued.
With this change, a given event can only have 1 executing instance at a
time (with the exception that the open-uri event doesn't go through this
mechanism).

The previous behavior was to always treat ctrl-alt as altgr on Windows,
this has been done to better support altgr through a VNC session,
but this is very unintuitive when you don't need this behavior.

This is to support <https://github.com/wez/wezterm/issues/291>.
The window resized event happens asynchronously wrt. processing
a window resize, triggering at the end of the normal window
resize handling.
This commit introduces the notion of whether we are in full screen
mode or not in the underlying event callback, which is useful to
gate the desired feature, which is: when in full screen mode,
increase the padding for the window to center its content.
While poking around at this, I noticed that we weren't passing
the per-window config down to the code that computes the quad
locations for the window.
This commit also changes the font size increase/decrease behavior
so that in full screen mode it doesn't try to resize the window.
```lua
local wezterm = require 'wezterm';
wezterm.on("window-resized", function(window, pane)
local window_dims = window:get_dimensions();
local pane_dims = pane:get_dimensions();
local overrides = window:get_config_overrides() or {}
if not window_dims.is_full_screen then
if not overrides.window_padding then
-- not changing anything
return;
end
overrides.window_padding = nil;
else
-- Use only the middle 33%
local third = math.floor(window_dims.pixel_width / 3)
local new_padding = {
left = third,
right = third,
top = 0,
bottom = 0
};
if overrides.window_padding and new_padding.left == overrides.window_padding.left then
-- padding is same, avoid triggering further changes
return
end
overrides.window_padding = new_padding
end
window:set_config_overrides(overrides)
end);
return {
}
```
I'm calling it a temporary defeat on the shaping changes;
this commit effectively reverts the series of changes made
to support slicing up ligatures like `->` when the cursor
moves through them.
They've introduced so many issues and I've spent hours
that haven't resulted in a complete solution, so I've
disabled those changes by putting them behind a boolean
option.
I'll revisit them after I've cut the next release.

Queries the system battery information and returns an array of
battery information.
Each element is a lua table with the following entries:
* state_of_charge: expressed as percents
* vendor: the battery manufacturer
* model: the battery model
* serial: the battery serial number
* time_to_full: how long until the battery is full
* time_to_empty: how long until the battery is empty
* state: "Charging", "Discharging", "Empty", "Full", "Unknown"
I haven't run this on a system with a battery yet, so I'm holding
off from showing an example until I've got a work one.

Manual test scenario:
```
wezterm -n --config adjust_window_size_when_changing_font_size=false --config 'exit_behavior="Hold"' start -- sh -c "echo '(...)'"
```
then CTRL +/- to change font size; the first cell of the `...` was
previously random garbage, now is more consistent.

I've kept resizing in there because it doesn't appear to render
a border in mutter and seems useful.
I think I'll probably change WindowDecorations to bitflags so
that the user can control this, but first need to verify what
windows supports for this.
mouse move events in the tab bar, and paint events, could cause
the title bar state to be recomputed.
Make sure that we don't trigger the status event to trigger for those.

I've only tested this on macos, but it should be cross platform,
with the caveat that Wayland doesn't let a window position itself,
so this won't work there.
