This allows you to treat any function that takes a `Rect` and a mutable
reference a `Buffer` as a widget in situations where you don't want to
create a new type for a widget.
Example:
```rust
fn hello(area: Rect, buf: &mut Buffer) {
Line::raw("Hello").render(area, buf);
}
frame.render_widget(&hello, frame.size());
frame.render_widget_ref(hello, frame.size());
```

Consensus is that explicit imports make it easier to understand the
example code. This commit removes the prelude import from all examples
and replaces it with the necessary imports, and expands other glob
imports (widget::*, Constraint::*, KeyCode::*, etc.) everywhere else.
Prelude glob imports not in examples are not covered by this PR.
See https://github.com/ratatui-org/ratatui/issues/1150 for more details.
`crossterm`, `termion`, and `termwiz` can now be accessed as
`ratatui::{crossterm, termion, termwiz}` respectively. This makes it
possible to just add the Ratatui crate as a dependency and use the
backend of choice without having to add the backend crates as
dependencies.
To update existing code, replace all instances of `crossterm::` with
`ratatui::crossterm::`, `termion::` with `ratatui::termion::`, and
`termwiz::` with `ratatui::termwiz::`.
This also results in a more readable Cargo.toml as the locations of the
things are more obvious now.
Includes rewording of the underline-color feature.

Simplify the List example by removing lifetimes not strictly necessary
to demonstrate how Ratatui lists work. Instead, the sample strings are
copied into each `TodoItem`. To further simplify, I changed the code to
use a new TodoItem::new function, rather than an implementation of the
`From` trait.
`List::start_corner` was deprecated in v0.25. Use `List::direction` and
`ListDirection` instead.
```diff
- list.start_corner(Corner::TopLeft);
- list.start_corner(Corner::TopRight);
// This is not an error, BottomRight rendered top to bottom previously
- list.start_corner(Corner::BottomRight);
// all becomes
+ list.direction(ListDirection::TopToBottom);
```
```diff
- list.start_corner(Corner::BottomLeft);
// becomes
+ list.direction(ListDirection::BottomToTop);
```
`layout::Corner` is removed entirely.

Codegen units are optimized on their own. Per default bench / release
have 16 codegen units. What ends up in a codeget unit is rather random
and can influence a benchmark result as a code change can move stuff
into a different codegen unit → prevent / allow LLVM optimizations
unrelated to the actual change.

Using reset is clearer to me what actually happens. On the other case a
struct is created to override the old one completely which basically
does the same in a less clear way.
It is sometimes useful to obtain access to the writer if we want to see
what has been written so far. For example, when using &mut [u8] as a
writer.

We need to make sure to not change existing methods without a notice.
But at the same time this also finds public additions with mistakes
before they are even released which is what I would like to have.
This renames a method and deprecated the old name hinting to a new name.
Should this be mentioned somewhere, so it's added to the release notes?
It's not breaking because the old method is still there.
- Simplify `assert_buffer_eq!` logic.
- Deprecate `assert_buffer_eq!`.
- Introduce `TestBackend::assert_buffer_lines`.
Also simplify many tests involving buffer comparisons.
For the deprecation, just use `assert_eq` instead of `assert_buffer_eq`:
```diff
-assert_buffer_eq!(actual, expected);
+assert_eq!(actual, expected);
```
---
I noticed `assert_buffer_eq!` creating no test coverage reports and
looked into this macro. First I simplified it. Then I noticed a bunch of
`assert_eq!(buffer, …)` and other indirect usages of this macro (like
`TestBackend::assert_buffer`).
The good thing here is that it's mainly used in tests so not many
changes to the library code.
- Rewrote the line / span rendering code to take into account how
multi-byte / wide emoji characters are truncated when rendering into
areas that cannot accommodate them in the available space
- Added comprehensive coverage over the edge cases
- Adds a benchmark to ensure perf

`Block::bordered()` is shorter than
`Block::new().borders(Borders::ALL)`, requires one less import
(`Borders`) and in case `Block::default()` was used before can even be
`const`.
