* docs: make library and README consistent
Generate the bulk of the README from the library documentation, so that
they are consistent using cargo-rdme.
- Removed the Contributors section, as it is redundant with the github
contributors list.
- Removed the info about the other backends and replaced it with a
pointer to the documentation.
- add docsrs example, vhs tape and images that will end up in the README
Fixes: https://github.com/ratatui-org/ratatui/issues/512
The bar values are not shown if the value width is equal the bar width
and the bar is height is less than one line
Add an internal structure `LabelInfo` which stores the reserved height
for the labels (0, 1 or 2) and also whether the labels will be shown.

This change simplifys UI code that uses the Frame type. E.g.:
```rust
fn draw<B: Backend>(frame: &mut Frame<B>) {
// ...
}
```
Frame was generic over Backend because it stored a reference to the
terminal in the field. Instead it now directly stores the viewport area
and current buffer. These are provided at creation time and are valid
for the duration of the frame.
BREAKING CHANGE: Frame is no longer generic over Backend. Code that
accepted `Frame<Backend>` will now need to accept `Frame`. To migrate
existing code, remove any generic parameters from code that uses an
instance of a Frame. E.g. the above code becomes:
```rust
fn draw(frame: &mut Frame) {
// ...
}
```
- add `Rect::is_empty()` that checks whether either height or width == 0
- refactored `Rect` into layout/rect.rs from layout.rs. No public API change as
the module is private and the type is re-exported under the `layout` module.
Adds a new `Block::border_set` method that allows the user to specify
the symbols used for the border.
Added two new border types: `BorderType::QuadrantOutside` and
`BorderType::QuadrantInside`. These are used to draw borders using the
unicode quadrant characters (which look like half block "pixels").
QuadrantOutside:
```
▛▀▀▜
▌ ▐
▙▄▄▟
```
QuadrantInside:
```
▗▄▄▖
▐ ▌
▝▀▀▘
```
Fixes: https://github.com/ratatui-org/ratatui/issues/528
BREAKING CHANGES:
- BorderType::to_line_set is renamed to to_border_set
- BorderType::line_symbols is renamed to border_symbols
* feat(line): add `Line::raw` constructor
There is already `Span::raw` and `Text::raw` methods
and this commit simply adds `Line::raw` method for symmetry.
Multi-line content is converted to multiple spans with the new line removed
An earlier change introduced a bug where the width of value labels with
unicode characters was incorrectly using the string length in bytes
instead of the unicode character count. This reverts the earlier change.

The `Spans` type (plural, not singular) was replaced with a more ergonomic `Line` type
in Ratatui v0.21.0 and marked deprecated byt left for backwards compatibility. This is now
removed.
- `Line` replaces `Spans`
- `Buffer::set_line` replaces `Buffer::set_spans`
Windows cannot compile termion, so it is not included in the docs.
Rustdoc will fail if it cannot find a link, so the docs fail to build
on windows.
This replaces the link to TermionBackend with one that does not fail
during checks.

The layout cache now uses a LruCache with default size set to 16 entries.
Previously the cache was backed by a HashMap, and was able to grow
without bounds as a new entry was added for every new combination of
layout parameters.
- Added a new method (`layout::init_cache(usize)`) that allows the cache
size to be changed if necessary. This will only have an effect if it is called
prior to any calls to `layout::split()` as the cache is wrapped in a `OnceLock`
This allows writing unit tests without having to call set_style on the
expected buffer.
E.g.:
```rust
use crate::style::Stylize;
let mut buf = Buffer::empty(Rect::new(0, 0, 10, 10));
buf.set_string(0, 0, "foo", Style::new().red());
buf.set_string(0, 1, "bar", Style::new().blue());
assert_eq!(buf, Buffer::with_lines(vec!["foo".red(), "bar".blue()]));
```

This commit adds `prelude::*` all doc examples and widget::* to those
that need it. This is done to highlight the use of the prelude and
simplify the examples.
- Examples in Type and module level comments show all imports and use
`prelude::*` and `widget::*` where possible.
- Function level comments hide imports unless there are imports other
than `prelude::*` and `widget::*`.
The Stylize trait was introduced in 0.22 to make styling less verbose.
This adds a bunch of documentation comments to the style module and
types to make this easier to discover.
Although the `Stylize` trait is already implemented for `&str` which
extends to `String`, it is not implemented for `String` itself. This
commit adds an impl of Stylize that returns a Span<'static> for `String`
so that code can call Stylize methods on temporary `String`s.
E.g. the following now compiles instead of failing with a compile error
about referencing a temporary value:
let s = format!("hello {name}!", "world").red();
BREAKING CHANGE: This may break some code that expects to call Stylize
methods on `String` values and then use the String value later. This
will now fail to compile because the String is consumed by set_style
instead of a slice being created and consumed.
This can be fixed by cloning the `String`. E.g.:
let s = String::from("hello world");
let line = Line::from(vec![s.red(), s.green()]); // fails to compile
let line = Line::from(vec![s.clone().red(), s.green()]); // works
A bug in the rendering caused the top line of the chart to be rendered
using the style of the chart, instead of the dataset style. This is
fixed by only setting the style for the width of the text, and not the
entire row.

- add format target to Makefile.toml that actually fixes the formatting
- rename fmt target to lint-format
- rename style-check target to lint-style
- rename typos target to lint-typos
- rename check-docs target to lint-docs
- add section to CONTRIBUTING.md about formatting
Putting the formatting and doc checks first to ensure that more critical
errors are caught first (e.g. a conventional commit error or typo should
not prevent the formatting and doc checks from running).
