Problem: 'breakindentopt' "min" works incorrectly with 'signcolumn'.
Solution: Use win_col_off() and win_col_off2().

Problem: #25826 added a (duplicate) sign comparison function, which was
modified and strayed from the original in #27418.
Solution: Merge the two functions and add a display test that actually
tests for this order in addition to the legacy tests.
Problem: Redrawing can be improved when inserting/deleting lines with 'number'.
Solution: Only redraw the number column of lines below changed lines.
Add a test as this wasn't previously tested.

Implement api_keydict_to_dict as the complement to api_dict_to_keydict
Fix a conversion error when nvim_get_win_config gets called from lua,
where Float values "x" and "y" didn't get converted to lua numbers.
Problem: LineNrAbove and LineNrBelow background wrong on wrapped lines.
Solution: Update number column also for wrapped part of a line.

Cherry-pick test_number.vim changes from patch 9.0.0626.
The "priority" field of extmarks can be used to set priorities of
extmarks which dictates which highlight group a range will actually have
when there are multiple extmarks applied. However, when multiple
extmarks have the same priority, the only way to enforce an actual
priority is through the order in which the extmarks are set.
It is not always possible or desirable to set extmarks in a specific
order, however, so we add a new "subpriority" field that explicitly
enforces the ordering of extmarks that have the same priority.
For now this will be used only to enforce priority of treesitter
highlights. A single node in a treesitter tree may match multiple
captures, in which case that node will have multiple extmarks set. The
order in which captures are returned from the treesitter API is not
_necessarily_ in the same order they are defined in a query file, so we
use the new subpriority field to force that ordering.
For now subpriorites are not documented and are not meant to be used by
external code, and it only applies to ephemeral extmarks. We indicate
the "private" nature of subpriorities by prefixing the field name with
an "_".
Problem: Marks moved by undo may be lost to "b_signcols.count".
Solution: Count signs for each undo object separately instead of
once for the entire undo.
Problem: Some core syntax highlight groups are cleared with intention to
always be shown without additional highlighting. This doesn't always
work as intended, especially with fallback mechanism of @-groups.
Example: `Statement`/`Keyword` group shown in help code blocks
(`@markup.raw`) is shown as bold (from `Statement`) cyan (from
`@markup.raw`) instead of bold grey.
Solution: Explicitly use normal grey foreground in syntax groups where
it was previously implicitly assumed.
Extmarks can contain URLs which can then be drawn in any supporting UI.
In the TUI, for example, URLs are "drawn" by emitting the OSC 8 control
sequence to the TTY. On terminals which support the OSC 8 sequence this
will create clickable hyperlinks.
URLs are treated as inline highlights in the decoration subsystem, so
are included in the `DecorSignHighlight` structure. However, unlike
other inline highlights they use allocated memory which must be freed,
so they set the `ext` flag in `DecorInline` so that their lifetimes are
managed along with other allocated memory like virtual text.
The decoration subsystem then adds the URLs as a new highlight
attribute. The highlight subsystem maintains a set of unique URLs to
avoid duplicating allocations for the same string. To attach a URL to an
existing highlight attribute we call `hl_add_url` which finds the URL in
the set (allocating and adding it if it does not exist) and sets the
`url` highlight attribute to the index of the URL in the set (using an
index helps keep the size of the `HlAttrs` struct small).
This has the potential to lead to an increase in highlight attributes
if a URL is used over a range that contains many different highlight
attributes, because now each existing attribute must be combined with
the URL. In practice, however, URLs typically span a range containing a
single highlight (e.g. link text in Markdown), so this is likely just a
pathological edge case.
When a new highlight attribute is defined with a URL it is copied to all
attached UIs with the `hl_attr_define` UI event. The TUI manages its own
set of URLs (just like the highlight subsystem) to minimize allocations.
The TUI keeps track of which URL is "active" for the cell it is
printing. If no URL is active and a cell containing a URL is printed,
the opening OSC 8 sequence is emitted and that URL becomes the actively
tracked URL. If the cursor is moved while in the middle of a URL span,
we emit the terminating OSC sequence to prevent the hyperlink from
spanning multiple lines.
This does not support nested hyperlinks, but that is a rare (and,
frankly, bizarre) use case. If a valid use case for nested hyperlinks
ever presents itself we can address that issue then.
'foldtext' can be set to an empty string to disable and render the
line with:
- extmark highlight
- syntax highlighting
- search highlighting
- no line wrapping
- spelling
- conceal
- inline virtual text
- respects `fillchars:fold`
Currently normal virtual text is not displayed

When an embedded Nvim instance changes its current directory a "chdir"
UI event is emitted. Attached UIs can use this information however they
wish. In the TUI it is used to synchronize the cwd of the TUI process
with the cwd of the embedded Nvim process.
Problem: Wrong "clear" argument passed to buf_signcols_count_range
when initializing "b_signcols.count" for the first time.
Solution: Pass kFalse so that the "nested" counter is not incorrectly
decremented.
Problem: The 'statuscolumn' is not redrawn on the wrapped part of a
line when moving the cursor with 'relativenumber' set.
Solution: Redraw the 'statuscolumn' for the entire line height in the
"col_rows" win_line() code path.
Problem: Some edge cases to the old (pre-#26406) and current "b_signcols"
structure result in an incorrectly sized "auto" 'signcolumn'.
Solution: * Implement a simpler 'signcolumn' validation strategy by immediately
counting the number of signs in a range upon sign insertion and
deletion. Decrease in performance here but there is a clear path
forward to decreasing this performance hit by moving signs to a
dedicated marktree, or by adding meta-data to the existing
marktree which may be queried more efficiently?
* Also replace "max_count" and keep track of the number of lines with
a certain number of signs. This makes it so that it is no longer
necessary to scan the entire buffer when the maximum number of signs
decreases. This likely makes the commit a net increase in performance.
* To ensure correctness we also have re-initialize the count for an
edited region that spans multiple lines. Such an edit may move the
signs within it. Thus we count and decrement before splicing the
marktree and count and increment after.
Problem: Current values of `StatusLine` and `StatusLineNC` are currently
designed to be visually distinctive while being not intrusive.
However, the compromise was more shifted towards "not intrusive".
After the feedback, statusline highlight groups should be designed to:
- Make current window clearly noticeable. Meaning `StatusLine` and
`StatusLineNC` should obviously differ.
- Make non-current windows clearly separable. Meaning `StatusLineNC`
and `Normal`/`NormalNC` should obviously differ.
Solution:
- Update `StatusLineNC` to have more visible background.
- Update `StatusLine` to be inverted variant of `StatusLineNC`.
- Update `WinBar` and `WinBarNC` to not link to `StatusLine` and
`StatusLineNC` because it makes two goals harder to achieve.
- Update `TabLine` to link to `StatusLineNC` instead of `StatusLine`
to not be very visually intrusive.
