Fixes https://github.com/zed-industries/zed/issues/18405
In https://github.com/zed-industries/zed/pull/18313, we introduced a
problem where git addition highlights might spuriously return when
undoing certain changes. It turned out, there were already some cases
where git hunk highlighting was incorrect when editing at the boundaries
of expanded diff hunks.
In this PR, I've introduced a test helper method for more rigorously
(and readably) testing the editor's git state. You can assert about the
entire state of an editor's diff decorations using a formatted diff:
```rust
cx.assert_diff_hunks(
r#"
- use some::mod1;
use some::mod2;
const A: u32 = 42;
- const B: u32 = 42;
const C: u32 = 42;
fn main() {
- println!("hello");
+ //println!("hello");
println!("world");
+ //
+ //
}
fn another() {
println!("another");
+ println!("another");
}
- fn another2() {
println!("another2");
}
"#
.unindent(),
);
```
This will assert about the editor's actual row highlights, not just the
editor's internal hunk-tracking state.
I rewrote all of our editor diff tests to use these more high-level
assertions, and it caught the new bug, as well as some pre-existing bugs
in the highlighting of added content.
The problem was how we *remove* highlighted rows. Previously, it relied
on supplying exactly the same range as one that we had previously
highlighted. I've added a `remove_highlighted_rows(ranges)` APIs which
is much simpler - it clears out any row ranges that intersect the given
ranges (which is all that we need for the Git diff use case).

This PR introduces functionality for creating *branches* of buffers that
can be used to preview and edit change sets that haven't yet been
applied to the buffers themselves.

Supersedes https://github.com/zed-industries/zed/pull/12090fixes#5180fixes#5055
See original PR for an example of the feature at work.
This PR changes the settings interface to be backwards compatible, and
adds the `ui_font_fallbacks`, `buffer_font_fallbacks`, and
`terminal.font_fallbacks` settings.
Release Notes:
- Added support for font fallbacks via three new settings:
`ui_font_fallbacks`, `buffer_font_fallbacks`, and
`terminal.font_fallbacks`.(#5180, #5055).

Closes https://github.com/zed-industries/zed/issues/4565
To fix issues with code blocks' parsing in Markdown, a
tree-sitter-markdown library update is needed.
But `tree_sitter::language` is used in many places within core Zed,
which forced more library updates.
Release Notes:
- Updated tree-sitter parsers for core languages

Note:
- We have disabled all tests that rely on Postgres in the Linux CI. We
only really need to test these once, and as macOS is our team's primary
platform, we'll only enable them on macOS for local reproduction.
- We have disabled all tests that rely on the font metrics. We
standardized on Zed Mono in many fonts, but our CoreText Text System and
Cosmic Text System proved to be very different in effect. We should
revisit if we decide to standardize our text system across platforms
(e.g. using Harfbuzz everywhere)
- Extended the condition timeout significantly. Our CI machines are slow
enough that this is causing spurious errors in random tests.

Release Notes:
- Improved expand excerpt indicators to allow unidirectional expansion.
Also added the `editor::ExpandExcerptsUp` and
`editor::ExpandExcerptsDown` actions, which can both take a `lines`
parameter. Also added a `expand_excerpt_lines` setting which controls
the default number of lines that the indicators and actions use.

This pull request replaces the static `⋯` character we used to insert
when folding a range with a custom render function that return an
`AnyElement`. We plan to use this in the assistant, but for now this
should be behavior-preserving.

Previously, when highlighting editor rows with a color, we always
auto-scrolled to the first highlighted row. This was useful in contexts
like go-to-line and the outline view. We had an explicit special case
for git diff highlights. Now, part of the `highlight_rows` API, you
specify whether or not you want the autoscroll behavior. This is needed
because we want to highlight rows in the assistant panel, and we don't
want the autoscroll.

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.

As an attempt to do things better when showing diff hunks, store diff
base as Rope, not String, to have cheaper clones when the diff base text
is reused, e.g. creating another buffer with the diff base text for hunk
diff expanding.

Added two new actions with the default keybindings
```
"cmd-'": "editor::ToggleHunkDiff",
"cmd-\"": "editor::ExpandAllHunkDiffs",
```
that allow to browse git hunk diffs in Zed:
https://github.com/zed-industries/zed/assets/2690773/9a8a7d10-ed06-4960-b4ee-fe28fc5c4768
The hunks are dynamic and alter on user folds and modifications, or
toggle hidden, if the modifications were not adjacent to the expanded
hunk.
Release Notes:
- Added `editor::ToggleHunkDiff` (`cmd-'`) and
`editor::ExpandAllHunkDiffs` (`cmd-"`) actions to browse git hunk diffs
in Zed

### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).
Release Notes:
- Fixed a bug that was causing popovers to flicker.
