For those who prefer to manage default options in a file.
If the file is not found, fzf will exit with an error.
We're not setting a default value for it because:
1. it's hard to find a default value that can be universally agreed upon
2. to avoid fzf having to check for the existence of the file even when it's not used

* Use `--unicode-placeholder` for consistent result in and out of tmux
* Use updated version of junegunn/go-runewidth that handles diacritics
used in Kitty Unicode placeholder

'transform' action runs an external command that prints a series of
actions to perform.
# Disallow selecting an empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"'
# Move cursor past the empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"' \
--bind 'focus:transform:[[ -n {} ]] && exit; [[ {fzf:action} =~ up$ ]] && echo up || echo down'

fzf --preview 'imgcat -W $FZF_PREVIEW_COLUMNS -H $FZF_PREVIEW_LINES {}'
Notes:
* There is no good way to determine the height of the rendered image,
so we assume that the image takes the full height of the preview
window. So the image cannot be displayed with the other text.
* fzf-preview.sh script was updated to use `imgcat` if it's available
but `chafa` is not.
* iTerm2 also supports Sixel, so adding support for this protocol is not
quite necessary but it renders animated GIFs much better (e.g. looping).

# FZF_API_KEY is required for a non-localhost listen address
FZF_API_KEY=xxx fzf --listen 0.0.0.0:6266

They are not neccessary because we can use a program such as chafa that
can resize images by the terminal columns and lines.

Progress:
* Sixel image can now be displayed with other text, and is scrollable
* If an image can't be displayed entirely due to the scroll offset, fzf
will render a wireframe to indicate that an image should be displayed
* Renamed $FZF_PREVIEW_{WIDTH,HEIGHT} to $FZF_PREVIEW_PIXEL_{WIDTH,HEIGHT}
for clarity
* Added bin/fzf-preview.sh script to demonstrate how to display an image
using Kitty or Sixel protocol
An example:
ls *.jpg | fzf --preview='seq $((FZF_PREVIEW_LINES*9/10)); fzf-preview.sh {}; seq 100'
A known issue:
* If you reduce the size of the preview window, the image may extend
beyond the preview window

# Scrolling will behave similarly to CTRL-E and CTRL-Y of vim
fzf --bind scroll-up:offset-up,scroll-down:offset-down \
--bind ctrl-y:offset-up,ctrl-e:offset-down \
--scroll-off=5

* Works inside and outside of tmux
* There is a problem where fzf unnecessarily displays the scroll offset
indicator at the topbright of the screen when the image just fits the
preview window. This is because `kitty icat` generates an extra line
after the image area.
# A 5-row images; an extra row at the end confuses fzf

* Example:
fzf --preview='
if file --mime-type {} | grep -qF 'image/'; then
# --transfer-mode=memory is the fastest option but if you want fzf to be able
# to redraw the image on terminal resize or on 'change-preview-window',
# you need to use --transfer-mode=stream.
kitty icat --clear --transfer-mode=memory --stdin=no --place=${FZF_PREVIEW_COLUMNS}x${FZF_PREVIEW_LINES}@0x0 {}
else
