Replace ios specific cfgs with "apple but not macOS", dubbed
ios_and_friends, so that we also cover iPadOS, etc.. What those have in
common is that they don't have user-resizable windows. (We might want to
add visionOs in the future)
Also, simplify a few macos or ios cfgs with just target_vendor =
"apple", for what applies to all the operating systems.
Enable the SDF feature by default in our compiler binaries
(Still disabled by default for other users because it takes up compile
time for something they probably don't need)
`__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
```
Added image-default-formats with all the format supported by image by
default, and enable that feature by default.
Also put that feature in compat-1-2 for compatibility with user that
have used image 0.24 with enabled features.
Make a new compat-1-10 feature that does not enable default format by
default
ChangeLog: upgraded image crate to 0.25, added a new cargo feature
to enable all image formats. (that feature is enabled by default with
compat-1-2, added compat-1-10 to disable it

* WIP: swrenderer: use fixed point for the pixmap font coordinate
* swrenderer: signed distance field: move the glyph to the middle
* swrenderer: round the advance instead of truncating it in distance field
* swrenderer: actually align the gplyph on the sub-pixel precision
sub-pixel within the source.
* swrenderer: adapt the threshold for signed distance field
sqrt(2) is the distance to the diagonal, seems like this gives sharper fonts
* Fix bug in the elision, and re-upload the screenshort
the screenshot changed because the afvanced is now rounded intead of
truncated
- include the ' ' char that doesn't have a bounding box but need to be
included for the advance_x
- Fix an off by one in rendering where the last pixel was missing
Initially the character map is ordered by glyph index. Maintain that order for glyph embedding, so that we can safely collect() the bitmaps. Just before creating the final BitmapFont data structure, sort by code point for fast lookups at run-time.
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).

The struct held provides access to the design metrics of the font scaled
to the font pixel size used by the element.
ChangeLog: Slint Language: Added font-metrics property to `Text` and `TextInput`.
Closes#6047
The test's build.rs invokes the compiler repeatedly with a configuration that enables font embedding. Instead of loading the same font with fontdue repeatedly (slow), store the loaded fonts in a hash table for re-use.
This should not have any impact on single file compilations, but it helps with the screenshot driver test dramatically, bringing down the time of
touch tests/screenshots/build.rs
cargo build -p test-driver-screenshots
on my xps13 linux from 1m26s to 15s.
Commit 3764312561 accidentally chained filter_map so that the list of default (fallback) fonts was empty. That resulted in
a simple hello world (with no custom fonts) embedding no font at all and causing a run-time error.
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
In the screenshot tests this works by setting SLINT_DEFAULT_FONT to
pointer to a directory, instead of a file. We then load all fonts in
that directory and consider their families the default unless a family
is specified. This way for "Noto Sans" a regular as well as an italic
version is registered in fontdb and returned in the list of font
fallback ids. embed_glyphs in the compiler then embeds those variants
and we find them at run-time.
As outlined in #2199, there may be ways to trigger text layout code
through forward-focus before embedded fonts are registered. To fix this,
this patch replaces the init_code vector, which had the SetFocusItem
code before the font registration, with three explicit vectors for focus
setup code, code from init callbacks, and initial focus, and defines the
order in one central place in the copmiler (iter()).
Fixes#2199
