https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

This PR fixes several possible memory leaks due to loading images in
markdown files and the image viewer, using the new image cache APIs
TODO:
- [x] Ensure this didn't break rendering in any of the affected
components.
Release Notes:
- Fixed several image related memory leaks
Closes#27414
`ImageCache` is independent of the original image loader and can
actively release its cached images to solve the problem of images loaded
from the network or files not being released.
It has two constructors:
- `ImageCache::new`: Manually manage the cache.
- `ImageCache::max_items`: Remove the least recently used items when the
cache reaches the specified number.
When creating an `img` element, you can specify the cache object with
`Img::cache`, and the image cache will be managed by `ImageCache`.
In the example `crates\gpui\examples\image-gallery.rs`, the
`ImageCache::clear` method is actively called when switching a set of
images, and the memory will no longer continuously increase.

This seems more correct as corners are not necessarily only for rounding
radii.
Also applies clamping after scaling in `paint_quad`, deduplicating that
logic. This also provides a more precise result by doing the clamping
after scaling, avoiding floating point rounding issues (probably a
non-issue).

Chatted with @as-cii about limitations in the `Window::parent_view_id()`
API (see:
https://github.com/zed-industries/zed/pull/24182/commits/662153dcfdd80804f4041761c09c4a309d79f6d4)
and realized that I shouldn't be using the dispatch tree's data
structures as they are layout dependent. I've introduced a new stack to
`Window`, `rendered_entity_stack`, that tracks exactly which view's
elements are being drawn. As such, I've also been able to remove the
`Option<>` around the previous API.

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!

- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`

@iamnbutler edit:
This pull request enhances the image element by introducing the ability
to display loading and fallback states.
Changes:
- Implemented the loading and fallback states for image elements using
`.with_loading` and `.with_fallback` respectively.
- Introduced the `StyledImage` trait and `ImageStyle` to enable a fluent
API for changing image styles across image types (`Img`,
`Stateful<Img>`, etc).
Example Usage:
```rust
fn loading_element() -> impl IntoElement {
div().size_full().flex_none().p_0p5().rounded_sm().child(
div().size_full().with_animation(
"loading-bg",
Animation::new(Duration::from_secs(3))
.repeat()
.with_easing(pulsating_between(0.04, 0.24)),
move |this, delta| this.bg(black().opacity(delta)),
),
)
}
fn fallback_element() -> impl IntoElement {
let fallback_color: Hsla = black().opacity(0.5);
div().size_full().flex_none().p_0p5().child(
div()
.size_full()
.flex()
.items_center()
.justify_center()
.rounded_sm()
.text_sm()
.text_color(fallback_color)
.border_1()
.border_color(fallback_color)
.child("?"),
)
}
impl Render for ImageLoadingExample {
fn render(&mut self, _cx: &mut ViewContext<Self>) -> impl IntoElement {
img("some/image/path")
.id("image-1")
.with_fallback(|| Self::fallback_element().into_any_element())
.with_loading(|| Self::loading_element().into_any_element())
}
}
```
Note:
An `Img` must have an `id` to be able to add a loading state.

We may only want to set the height of an image to limit the size and
make the width adaptive.
In HTML, we will only set width or height, and the other side will adapt
and maintain the original image ratio.
I changed this because I had a logo image that only to be limited in
height, and then I found that setting the height of the `img` alone
would not display correctly.
I also tried to set `ObjectFit` in this Demo, but it seems that none of
them can achieve the same effect as "After".

This PR is a refactor to pave the way for allowing the user to view and
edit workflow step resolutions. I've made tool calls work more like
normal streaming completions for all providers. The `use_any_tool`
method returns a stream of strings (which contain chunks of JSON). I've
also done some minor cleanup of language model providers in general,
removing the duplication around handling streaming responses.

Currently, the `img` element provided by GPUI only supports FilePath or
URL, but in actual applications we need to let `img` load an image
embedded in Assets.
The `svg` element can currently support this, but `img` cannot.
For example:
We have such an Assets directory:
```
assets
|- icons
|- images
|--- foo.png
```
```rs
// If give a path, considered an Asset
img("images/foo.png");
// If give a URI, considered a Remote image
img("https://foo.bar/images/foo.png");
// If give a PathBuf, considered a Local file
img(PathBuf::from("path/to/foo.png"));
```
## Example test
```
cargo run -p gpui --example image
```
<img width="827" alt="image"

This PR adds support for animated images. The image requires a id for it
to actually animate across frames.
Currently it only has support for `GIF`, I tried adding decoding a
animated `WebP` into frames but it seems to error. This issue in the
image crate seems to document this
https://github.com/image-rs/image/issues/2263.
Not sure if this is the best way or the desired way for animated images
to work in GPUI but I would really like support for animated images.
Open to feedback.

Bumping the image crate for better support of image formats.
The latest version does not have a `BGRA` type it only has `RGBA` it
doesn't really matter as the size is the same but the type name is a
little confusing as we need it as `BGRA`. Also there is no `into_bgra8`
but we can use `into_rgba8` but then it must be converted before
creating the `ImageData`.

We're planning to associate "selection sources" with global element ids
to allow arbitrary UI text to be selected in GPUI. Previously, global
ids were not exposed outside the framework and we entangled management
of the element id stack with element state access. This was more
acceptable when element state was the only place we used global element
ids, but now that we're planning to use them more places, it makes sense
to deal with element identity as a first-class part of the element
system. We now ensure that the stack of element ids which forms the
current global element id is correctly managed in every phase of element
layout and paint and make the global id available to each element
method. In a subsequent PR, we'll use the global element id as part of
implementing arbitrary selection for UI text.

The new `ElementContext` was originally introduced to ensure the element
APIs could only be used inside of elements. Unfortunately, there were
many places where some of those APIs needed to be used, so
`WindowContext::with_element_context` was introduced, which defeated the
original safety purposes of having a specific context for elements.
This pull request merges `ElementContext` into `WindowContext` and adds
(debug) runtime checks to APIs that can only be used during certain
phases of element drawing.

This pull request introduces the new
`ElementContext::request_autoscroll(bounds)` and
`ElementContext::take_autoscroll()` methods in GPUI. These new APIs
enable container elements such as `List` to change their scroll position
if one of their children requested an autoscroll. We plan to use this in
the revamped assistant.
As a drive-by, we also:
- Renamed `Element::before_layout` to `Element::request_layout`
- Renamed `Element::after_layout` to `Element::prepaint`
- Introduced a new `List::splice_focusable` method to splice focusable
elements into the list, which enables rendering offscreen elements that
are focused.

While working towards fixes for the image viewer, @mikayla-maki and I
discovered that we didn't have `object-fit: scale-down` implemented.

chased down.

PR: #9931 broke image scaling, such that it ignores the object-fit
parameter and instead always scales the image to fit the bounds. This
fixes the regression.
This is a follow up to #9436 . It has a cleaner API and generalized the
image_cache to be a generic asset cache, that all GPUI elements can make
use off. The changes have been discussed with @mikayla-maki on Discord.

Release Notes:
- Added [object-fit
API](https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit) to the
`img` element. This allows the user to decide how the image is scaled
within the element bounds.
- Fixes corner radius not working as expected on overflowing elements.

### 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.

This PR is a follow-up to #7084, where I noted that I wasn't satisfied
with using `SharedUri` to represent both URIs and paths on the local
filesystem:
> I'm still not entirely happy with this naming, as the file paths that
we can store in here are not _really_ URIs, as they are lacking a
protocol.
>
> I want to explore changing `SharedUri` / `SharedUrl` back to alway
storing a URL and treat local filepaths differently, as it seems we're
conflating two different concerns under the same umbrella, at the
moment.
`SharedUri` has now been reverted to just containing a `SharedString`
with a URI.
`ImageSource` now has a new `File` variant that is used to load an image
from a `PathBuf`.

This PR implements support for loading and displaying images from a
local file using gpui's `img` element.
API Changes:
- Changed `SharedUrl` to `SharedUrl::File`, `SharedUrl::Network`
Usage:
```rust
// load from network
img(SharedUrl::network(...)) // previously img(SharedUrl(...)
// load from filesystem
img(SharedUrl::file(...))
```
This will be useful when implementing markdown image support, because we
need to be able to render images from the filesystem (relative/absolute
path), e.g. when implementing markdown preview #5064.
I also added an example `image` to the gpui crate, let me know if this
is useful. Showcase:
<img width="872" alt="image"
