* Update to rust 1.60.0
* Rename the feature `convert_bytemuck` to `bytemuck`
* Rename the feature `serialize` to `serde`.
* Make use of the "weak dependency" cargo feature
* Set rust-version = "1.60" for all crates
* egui_glow: clipboard, links, persistence & winit are now opt-in features
The purpose of this is to expose `frame.storage()` and `frame.storage_mut()` so users can save/load app state from the `App::update` function, without having to add another parameter to that function.
Changes:
* Added `Frame::storage()` and `Frame::storage_mut()`
* `App::update` now takes a `&mut Frame` rather than just `&Frame`
* `Frame` is no longer `Clone` or `Sync` (doesn't have to be since https://github.com/emilk/egui/pull/1366)
* Rename AlphaImage to FontImage to discourage any other use for it
* Encode FontImage as f32 and postpone the alpha correction
* Interpret alpha coverage in a new, making dark text darker, improving contrast in bright mode
The epaint tessellator uses "feathering" to accomplish anti-aliasing. This PS allows you to control the feathering size, i.e. how blurry the edges of epaint shapes are.
This changes the interface of Tessellator slightly, and renames some options in TessellationOptions.
* Expose more tessellator method
* Make public the Tessellator methods to tessellate a circle, a
mesh, a rectangle, a line, a path, a quadratic and cubic
bezier curve.
* Add doc to tessellate_text.
* Add Mesh::append_ref method.
* Make tessellate_text take a reference
* Fix breaking change in benchmark
* Add Shape::Callback to do custom rendering inside of an egui UI
* Use Rc<glow::Context> everywhere
* Remove trait WebPainter
* Add glow::Context to epi::App::setup
This comes at the cost of these corners sometimes becoming badly
extruded instead. The sharper the corner, the bigger the problem.
A proper fix will have to wait for later.
Part of https://github.com/emilk/egui/issues/1226
* egui_web: use tracing crate
* egui_glow: use tracing crate
* Log at the debug level
* egui_demo_app: enable tracing to log to stdout
* Use tracing in egui-winit
* Add opt-in tracing support to egui
In https://github.com/emilk/egui/pull/1154 the default was set to
16k x 512, which is way excessive, as most of it will be blank.
This PR changes it to 8k x 64, which will make egui
use less RAM and VRAM, and load quicker again.
This also decreases the max size from 16k² to 8k².
That should be enough.
* Refactor text layout: don't need &Fonts in all functions
* Replace indexing in Fonts with member function
* Wrap Fonts in a Mutex
* Remove mutex for Font::glyph_info_cache
* Remove RwLock around Font::characters
* Put FontsImpl and GalleyCache behind the same Mutex
* Round font sizes to whole pixels before deduplicating them
* Make TextStyle !Copy
* Implement user-named TextStyle:s
* round font size earlier
* Cache fonts based on family and size
* Move TextStyle into egui and Style
* Remove body_text_style
* Query graphics about max texture size and use that as font atlas size
* Recreate texture atlas when it is getting full
