This PR adjusts our font resolution code to attempt to use a fallback
font if the specified font cannot be found.
Right now our fallback font stack is `Zed Mono`, followed by `Helvetica`
(in practice we should always be able to resolve `Zed Mono` since we
bundle it with the app).
In the future we'll want to surface the ability to set the fallback font
stack from GPUI consumers, and potentially even support specifying font
stacks in the user settings (as opposed to a single font family).
Release Notes:
- Fixed a panic when trying to load a font that could not be found.
After implementing it a while ago, our previous interpolation scheme
didn't really make sense to me and was causing borders to be rendered
incorrectly. We don't really draw backgrounds and borders as part of
the same draw call anymore, but it seemed reasonable to have a correct
implementation in the shader anyway.
This commit uses Porter-Duff compositing (i.e., `over`) to produce
a color that is the result of superimposing the border on top of the
background. Then, we linearly interpolate towards the background color
as we slide out of the border and into the background.
**This PR also bumps wasmtime version from 0.38 to 2.0 as 0.38 does not
build with Rust 1.75**. I did not test the plugin runtime as (AFAIK) we
intend to deprecate it; also, wasmtime's most recent version is 16.0, so
it'd make sense to bump the version at some point anyways. I did not
bump the version to 16.0 straight away as that'd require code changes in
`plugin_runtime`.
Release Notes:
- N/A
Release Notes:
- Added documentation display for autocomplete items.
- Fixed autocomplete filtering blocking the Zed UI, causing hitches and
input delays with large completion lists.
- Fixed hover popup link not firing if the mouse moved a slight amount
while clicking.
- Added support for absolute path file links in hover popup and
autocomplete docs.
This PR mainlines the current state of new GPUI2-based UI from the
`gpui2-ui` branch.
Included in this is a performance improvement to make use of the
`TextLayoutCache` when calling `layout` for `Text` elements.
Release Notes:
- N/A

This PR improves the error message when `FontCache.load_family` attempts
to load a font that is not present on the system.
I ran into this while trying to run the `storybook` for the first time.
The error message indicated that a font family was not found, but did
not provide any information as to which font family was being loaded.

Release Notes:
- N/A
This PR puts the `Theme` returned from the `theme` function behind an
`Arc`.
### Motivation
While working on wiring up window focus events for the `TitleBar`
component we ran into issues where `theme` was holding an immutable
borrow to the `ViewContext` for the entirety of the `render` scope,
which prevented having mutable borrows in the same scope.
### Explanation
To avoid this, we can make `theme` return an `Arc<Theme>` to allow for
cheap clones and avoiding the issues with the borrow checker.
Release Notes:
- N/A
