Sixel can only represent transparency for fully transparent (alpha
= 0) and fully opaque (alpha = 255) pixels, i.e. we would have to
do blending ourselves to do this "properly". But what do you even
blend? Background color? Images? Clearly you can't do text...
So instead of going down the blending route, we now just approximate
the 8-bit channel with Sixel's 1-bit channel and then patch it up with
dither. It does look a bit weird, but it's not *that* bad, especially
compared to the previous strategy of "blend with some color which
hopefully happens to be the background color" (it rarely was).
Note that this requires us to handle transparent images specially
in term. That is, for opaque ones, we can leave out the "clear cells
affected by image" part, but for transparent ones, we must clear the
entire image every time.

* align status truncating behavior with w3m (not exactly, clipping
is still different, but this should be fine for now)
* add "su" for "show last alert"
- w3m's solution here is to scroll one char at a time with
"u", but that's extremely annoying to use. We already have a
line editor that can navigate lines, so reuse that instead.
* fix peekCursor showing empty text
* update todo

in fact, we consider these to be the same image, and arguably that's
a bug in and of itself. but at least we don't crash anymore.
(also, update todo)

Still not perfect, because it crashes on missing /tmp dir so you have to
manually set it...

We were not setting the invalid flag on bitmap load, so any incremental
reshape could interfere with displaying images that got loaded after
the reshape.

Mainly things you could already set with [[siteconf]] but not normally.
Also, a `styling' option to disable author styles.
Also, `images' is now documented as an "experimental" option, since it's
halfway usable now.

* multi-processed and sandboxed PNG decoding & encoding (through local
CGI)
* improved request body passing (including support for output id as
response body)
* simplified & faster blob()/text() - now every request starts
suspended, and OngoingData.buf has been replaced with loader's
buffering capability
* image caching: we no longer pull bitmaps from the container after
every single getLines call
Next steps: replace our bespoke PNG decoder with something more usable,
add other decoders, and make them stream.

If the total specified column width is larger than the table's allowed
width, we now resize them proportionally to the specified width.
This is quite important because many tables set the width to e.g. 50%
for "give me half of the table", instead of its true meaning "give me
half of the page".

* png: add missing filters, various decoder fixes
* term: fix kitty response interpretation, add support for kitty image
detection
* buffer, pager: initial image display support
Emphasis on "initial"; it only "works" with kitty output and PNG input.
Also, it's excruciatingly slow, and repaints images way too often.
Left undocumented intentionally it for now, until it actually becomes
useful. In the meantime, adventurous users can find out themselves why:
[[siteconf]]
url = "https://.*"
images = true

It's a bad idea for several reasons:
* it's inefficient; must allocate an environment for a closure in Nim,
even though we already have one in JS
* writing macros for automatically creating functions with variadic
arguments is suprisingly difficult (see the entire `js/javascript'
module)
* it never really worked properly, because we never freed the associated
function pointer.
We hardly used it anyway, so the easiest fix is to get rid of it
completely.

it's better than nothing. I suppose.
(Two-value flex syntax is encouraged even by the standard, so it gets
used a lot, and that sets 0, not flex-basis: auto, so not having
flex-basis breaks too many things.)

Still far from being fully standards-compliant, or even complete, but it
seems to work slightly less horribly than having no flexbox support at
all on sites that do use it.
(Also includes various refactorings in layout to make it possible at all
to add flexbox.)

Depending on Perl just for this is silly.
Now we use libregexp for filtering basically the same things as
w3mman2html did. This required another patch to QuickJS to avoid
pulling in the entire JS engine, but in return, we can now run regexes
without a dummy JS context global variable.
Also, man.nim now tries to find a man command on the system even if it's
not in /usr/bin/man.

The previous retrofitting of the old renderdocument error correction
usually worked, but it still had a horrible flaw in that it assumed that
all line boxes are of equal height. So if error was lower for some line
than another, it would move *all* lines by a somewhat lower error, and
that resulted in overlapping lines.
Now we do something much simpler: in flushLine, round each line's height
downwards before moving on to the next line. This gets rid of any blanks
inbetween lines, and also works much better with cleared floats.

derived from w3mman2html.cgi, there are only a few minor differences:
* different man page opener command
* use man:, man-k:, man-l: instead of query string to specify action
* no form input (C-lC-uman:pageC-m is faster anyway)
TODO rewrite in Nim so we don't have to depend on Perl...

* better path handling done
* empirically, we no longer crash on / -> M-c
* LD_PRELOAD is good enough, especially now when the main binary no
longer links to libcurl

It's not perfect still, but with newer Nim versions the browser
compiles in about 20 secs on my machine (a signficiant improvement
over what used to be like 50 secs or something). No need to keep this
