So that it can determine if it should subtract 1 from $FZF_PREVIEW_LINES
to avoid scrolling issue of Sixel image that touches the bottom of the
screen.
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
Close#3228
* 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

Currently there is not option to bind ctrl-delete and shift-delete. As
suggested by issue #3240, shift-delete could be used to bind "delete
entry from history" as it is a common way to do so in other
applications, e.g. browsers.
This, however, does only implement to use the key combination itself and
does not assign a default action to any of them. This does enable to
call one's all predefined actions. With the exec action this can
expanded like the issue #3240 suggested.
If desirable, the key combinations could later get a default behavior.

Can we find a better name? I have considered the followings.
* 'point', because "the pointer" points to the current item.
* 'shift', 'switch', 'move', etc. These are not technically correct
because the current item can change without cursor movement (--tac,
reload, search update)
* 'change' is already taken. 'change-current' feels a bit wordy and
sounds wrong, 'current-changed' is wordy and doesn't go well with the
other event names
* 'target', not straightforward
Close#3053
* Default border style on Windows is changed to `sharp` because some
Windows terminals are not capable of displaying `rounded` border
characters correctly.
* If your terminal emulator renders each box-drawing character with
2 columns, set `RUNEWIDTH_EASTASIAN` environment variable to `1`.
