Up until now, we’ve always re-rendered the entire image (the part of
it that is visible at least), *every* time we render a frame.
This is not really needed. In many cases, the cells covered by the
image hasn’t been touched.
Rewrite the sixel rendering code to only render the part of the sixel
image that covers dirty cells.
This is done on a per-row basis. I.e. Each *row* of the image that
covers at least one dirty cell is re-rendered. For this to work, we
now also dirty all cells covered by the image when we emit the image.
Finally, for this to work, the sixels need to be rendered *before* we
do the normal grid render pass (since that will clear all dirty bits).
When num lock override has been enabled via “CSI?1035h” (the default),
keypad is always considered to be in ‘numerical’ mode.
This affects how keypad keys are translated to escape sequences when
Num Lock is active.
The keypad has four modes:
* Num Lock off, numerical mode
* Num Lock off, application mode
* Num Lock on, numerical mode
* Num Lock on, application mode
The keymap is identical for numerical and application mode when Num
Lock is off, meaning the keypad effectively has three different modes.
In XTerm, numerical and application mode _can_ be the same, **if** the
‘numLock’ resource is set to true (the default). It is only when
‘numLock’ is false that the application mode is actually used.
This patch changes foot to do the same. We don’t expose an option, but
do implement “CSI ? 1035”.
Closes#194
A configure event must be “committed”. In case of resizing, that means
rendering a new frame and committing that surface.
render_resize() will resize the grid and *schedule* a render
refresh. However, if one is already pending, the refresh will take a
very (relatively) long time - until the next frame callback is
received.
This poses a problem when the window is hidden, since in this case,
the frame callback *never* comes. This in turn means we fail to commit
a new surface in response to the ‘configure’ event. And that means the
compositor needs to wait for a transaction timeout before continuing.
The end effect is very slow and jerky window resizing when a hidden
foot window is being resized.
This can happen in tiled compositors, like Sway, where a window can be
tabbed (and thus invisible), but still resized when its container is
resized.

- zsh doesn't like "export var+=value", make it two steps
- meson was complaining with "ERROR: Must specify at least one directory name.", so add the relative "../.."
enum selection_scroll_direction is used when extending a selection by
auto-scrolling the terminal content while the mouse is outside the
grid.
What we want is enum selection_direction.

When converting mouse scroll events to keyboard input (in alternate
scroll mode), we need to use seat->mouse_focus, not seat->kbd_focus.
To enable this, break out key press/release handling code to a
separate function that takes an explicit term argument. Call this
function from keyboard_key(), input_repeat() and in alternate scroll
mode.

On some platforms, TIOCSWINSZ has a very large value, >
0x80000000.
On some platforms, the `request` argument to `ioctl(3)` is an `int`.
For platforms where both of the above is true, gcc will warn (and
error out if compiled with `-Werror`) on:
ioctl(fd, TIOCSWINSZ, ...)
To silence this warning, we need to cast `TIOCSWINSZ` to an
integer.
However, doing this on platforms where `request` is an `unsigned long`
will result in `TIOCSWINSZ` being sign-extended (and thus we end up
with an invalid value).
It seems that casting to `unsigned int` works in both cases; it
silences the long -> int conversion warning, while also preserving the
correct value in all cases.
* Don’t de-reference the xkb context/keymap/state if we failed to
instantiate them.
* Don’t try to send a translated utf8 key sequence if the translation
failed.
* Handle xkb_compose_state_get_utf8() and xkb_state_key_get_utf8()
returning more than 64 bytes.
This _may_ fix#171.
Bind to xdg-shell version 2 if available, as this enables us to
track our window’s ‘tiled’ state in the ‘configure’ events.
This in turn allows us to stash the ‘old’ window size when being
tiled, to be used again when restoring the window size when un-tiled.
Handle xkb_compose_table_new_from_locale() returning NULL. When this
happens, log a warning that “dead keys” will be disabled, and make
sure to never de-reference the compose table pointer.

These bindings copy from the clipboard or primary selection into the
search buffer.
Default bindings:
* clipboard-paste: ctrl+v, ctrl+y
* primary-paste: shift+insert
The intention here is to make *all* text_from_clipboard() and
text_from_primary() callers benefit from mime-type base
decoding (e.g. URI list decoding).
Previously, the decoding was done *in* the callback, which meant only
the “default” clipboard/primary selection paste functions, and DnD,
recognized URI lists.
