Re-applies https://github.com/zed-industries/zed/pull/30840
This PR re-applies the initial
[PR](https://github.com/zed-industries/zed/pull/30840). As it was closed
because it was hard to land, because of the many conflicts. This PR
re-applies the changes for it.
In several cases we were creating multiple display_map
snapshots within the same root-level function call.
Creating a display_map snapshot is quite slow, and in some
cases we were creating the snapshot multiple times.
Release Notes:
- N/A
Closes#5355
Release Notes:
- Fixed rendering glitches with files with more than 16 million lines
(that occured due to floating number rounding errors).

When the selection grows both ways, the new code prioritizes the top
part instead of bottom one, this is usually more helpful considering
that most programming language grammars tend to define tokens right
before large delimited blocks, and rarely after (because humans and
parsers read from top to bottom).
Also, revert selection when convenient, so you have more control over
what you're selecting, looking at the selection `head` is commonly more
convenient than at the `tail`.
Release Notes:
- Improve scrolling of `editor::SelectLargerSyntaxNode` for better
visibility.
This is the core change:

TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code
Release Notes:
- N/A
There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue
Release Notes:
- N/A

On top of `editor::ScrollCursorCenter`, `editor::ScrollCursorTop`,
`editor::ScrollCursorBottom` actions, adds an
`editor::ScrollCursorCenterTopBottom` one, that allows using a single
keybinding to scroll between positions on the screen.
The implementation matches a corresponding Emacs feature: there's a
timeout (1s) that is kept after every switch, to allow continuously
changing the positions, center (initial) -> top -> bottom
Scrolling behavior is the same as the existing actions (e.g. editor will
ignore scroll to bottom, if there's not enough space above).
After 1s, next position is reset to the initial, center, one.
Release Notes:
- Added an `editor::ScrollCursorCenterTopBottom` action for toggling
scroll position with a single keybinding

Part of https://github.com/zed-industries/zed/issues/8081
To avoid confusion and bugs when converting between various row `u32`'s,
use different types for each.
Further PRs should split `Point` into buffer and multi buffer variants
and make the code more readable.

After #2641 we noticed that scrolling didn't take a count parameter.
The PageDown/PageUp logic was also broken by an additional -1 (for both
vim mode and not).
