* 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
* 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 window building to egui-winit
* Move icon loading to egui-winit
* `use glow::HasContext;` -> `use glow::HasContext as _;`
* Move FileStorage into epi behind a feature flag
* De-duplicate screen_size_in_pixels and native_pixels_per_point
* Move creation of FileStorage to epi
* Handle epi app output (window size changes etc) in egui-winit
* Move app and memory persistence and autosave logic to egui-winit
* fix check.sh
* Make the epi backend opt-in for egui_glium and egui_glow
* Fix persistence
* Add integration name to epi::IntegrationInfo and the demo
* Clean up Cargo.toml files and fix making egui_glium optional
* fix typo
* Make egui_glium compile without the `epi` feature
* add texture registering function
* fmt
* Revert "add texture registering function"
This reverts commit f9b4db12
* make get_texture public to get render target owned by Painter .
* revert egui_web painter.rs change
* Added shaders on GLSL 1.2
- Used `glium::program` to create shaders
- Moved shaders code to its own sources and include it as str
- Added shaders implementation on GLSL which allows run egui on old hardware
(Raspberry Pi 1/zero in game again)
* Moved webgl shaders code to sources in `shader` subdir
* Added GLSL ES shaders to glium backend to support OpenGL ES
* Described changes related to GLSL versions support
* Make `egui_glium::painter::Painter::paint_job` pub
The background is: I'm working on an engine where I would like to draw the gui and the game to the same `glium::Frame`. Haven't found any other obvious, trivial solution. I could of course write my own integration, but I just think this makes sense to be public.
* Make two other necessary functions public
