- Implement @conic-gradient(color angle, ...) syntax
- Center is always at rectangle center (no center_x/center_y parameters)
- 0 degrees starts at north (12 o'clock position)
- Support Slint angle units: deg, rad, turn
- Software renderer: Full native implementation
- Qt backend: Native support with angle offset correction
- Skia backend: Native support with angle offset correction
- FemtoVG backend: Fallback to solid color (first gradient stop)
ChangeLog: Added support for `@conic-gradient`
Fixes#3957
* syntax_tests: allow to "bless" tests, and don't use a regexp
A regexp was used at the beginning because I thought we would want to
allow error to contains things that were not predictable or that would
often change. But this is not the case¹. It is better to actually test
for the full error message
¹ well actually it was the case for path, but there is another substitution to
`📂` for the manifest directory
* syntax_tests: Bless the tests
* syntax_tests: Manual adjust after bless
Because there used to be comments on the same line of the message which
bless don't support
* Fix error message with path on windows
- The debug implementation of path make double slash, that's not what
we want to show the user
- normalize paths to use `/` so the test passes
In the test, `reexport.slint` depends on `bar.slint`
When parsing `reexport.slint` we shouldn't clear previously reported
error from previously parsed `bar.slint`. The errors are still there.
`__CARGO_FIX_YOLO=1` is a hack, but it does help a lot with the tedious fixes where the result is fairly clear.
See https://rust-lang.github.io/rust-clippy/master/index.html#/needless_borrow
```
__CARGO_FIX_YOLO=1 cargo clippy --fix --all-targets --workspace --exclude gstreamer-player --exclude i-slint-backend-linuxkms --exclude uefi-demo --exclude ffmpeg -- -A clippy::all -W clippy::needless_borrow
cargo fmt --all
```
This is a hacky approach, but does help a lot with the tedious fixes.

Only the interpreter is implemented so far
MacOs won't work yet because we don't disable the default winit menubar
The viewer don't support removing the MenuBar yet
The idea of the live-preview is that it never causes disk
access itself, the LSP side handles all that for it.
With this in mind:
* Keep source code of invalidated files in the cache. This
way we will see whether we need to refresh the UI after the
LSP has read the data back from disk. This avoids quite
a bit of rerendering just because an unchanged buffer was
closed in the editor (e.g. because the editor switched buffers!)
* Always return `Some` from our file open fallback so that the
compiler does not fall back to reading data from disk
* Do not try to render if the main file has no source code yet.
The LSP will tell us about the sources in time
The change in https://github.com/slint-ui/slint/pull/6747
invalidated the cache, but it was only reloaded when one of the dependent was reloaded.
We need to reload the cache for all open file so that LSP feature continue to work on
open document even if they get no changes
Don't filter type import with the extension. Instead if the import
statement is having braces, always consider it is a slint file, and if
not, consider it as a foreign import
Do not extract the file loading into a fuinction: That keeps
`self` around which is part of a borrowed state. That is a
problem as during the load we end up in `ensure_document_loaded`
again, which will try to borrow_mut that same state.
This removes a lot of allocations and speeds up the compiler step
a bit. Sadly, this patch is very invasive as it touches a lot of
files. That said, each individual hunk is pretty trivial.
For a non-trivial real-world example, the impact is significant,
we get rid of ~29% of all allocations and improve the runtime by
about 4.8% (measured until the viewer loop would start).
Before:
```
Benchmark 1: ./target/release/slint-viewer ../slint-perf/app.slint
Time (mean ± σ): 664.2 ms ± 6.7 ms [User: 589.2 ms, System: 74.0 ms]
Range (min … max): 659.0 ms … 682.4 ms 10 runs
allocations: 4886888
temporary allocations: 857508
```
After:
```
Benchmark 1: ./target/release/slint-viewer ../slint-perf/app.slint
Time (mean ± σ): 639.5 ms ± 17.8 ms [User: 556.9 ms, System: 76.2 ms]
Range (min … max): 621.4 ms … 666.5 ms 10 runs
allocations: 3544318
temporary allocations: 495685
```
Have a warning when a component is exported from the main file and
doesn't inherit Window.
Unless it's the last component, for compatibility with Slint 1.6
Also don't warn in the interpreter
Preparation for multi-components
Note that this had to rename one instance of TextStyle because it
conflicts with the struct of the same name used in the FontSettings
in the style. This wasn't a problem before because it shares some
property in common, and the the order of processing of component has
changed leading to the other one being generated.
(But that is a wider bug in the compiler outside of the scope of this
refactoring)
Use this snapshot to keep a unoptimized typeloader around, so that the preview
does not need to do another parsing run.
Move the document cache in the preview over to use the snapshot.
