* 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
* Move texture allocation into epaint/egui proper
* Add TextureHandle
* egui_glow: cast using bytemuck instead of unsafe code
* Optimize glium painter
* Optimize WebGL
* Add example of loading an image from file
* Move all interior mutability from Context to CtxRef and make it a handle
* Rename `CtxRef` to `Context`
* The old `Context` is now `ContextImpl` and is non-pub
* Add benchmark Painter::rect
