This adds a callback (set by `Context::set_request_repaint_callback`)
which integration can use to wake up the UI thread.
eframe (egui_web and egui_glow) will use this, replacing
`epi::Frame::request_repaint`.
Existing code calling `epi::Frame::request_repaint` should be changed
to instead call `egui::Context::request_repaint`.
This is the first callback added to the egui API, which otherwise is
completely driven by data.
The purpose of this is to remove the confusion between the two
`request_repaint` methods (by removing one). Furthermore, it makes
`epi::Frame` a lot simpler, allowing future simplifications to it
(perhaps no longer having it be `Send+Sync+Clone`).
* 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
* egui_web: always use the glow painter, and remove the old WebGL code.
* Clean up the WebPainter trait
* Clarify WebGL1 warning text in color test
The glow painter became standard in egui 0.17, and I've heard no complaints! So let's simplify and go all in on glow.
Part of https://github.com/emilk/egui/issues/1198
This adds all parts of the web "location" (URL) to frame.info().web_info, included a HashMap of the query parameters, percent-decoded and ready to go.
This lets you easily pass key-value pairs to your eframe web app.
Since https://github.com/emilk/egui/pull/1149 we only update the
region of the font atlas that has changes, so loading new glyphs is much
cheaper. This means warm-up is much less needed.
There is now a small delay when opening the font book,
but not when opening anything else.
* Fix Orientation not exposed, although there are public fields with its type
* Implement formatters for X/Y axis labels
* Use array instead of separate X/Y formatters
* Swap axis formatters if charts are horizontal
* Review suggestions
* 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

This is a good early-out for widgets in `ScrollAreas`, but
also prepares for speeding up the first pass of a possible two-pass
version of egui: https://github.com/emilk/egui/issues/843
* Rename `CursorPair` to `CursorRange`
* Easymark editor: add keyboard shortcuts to toggle bold, italics etc
* Split up TextEdit into separate files
* Add TextEdit::show that returns a rich TextEditOutput object with response, galley and cursor
* Rename text_edit::State to TextEditState
This refactors the widget state storage introduced by @optozorax in https://github.com/emilk/egui/pull/257
* Unify the four buckets (`data`, `data_temp`, `id_data` and `id_data_temp`) into a single `data`.
* Less complexity, and also less chance of error (storing in one bucket, reading from another).
* Store data by `Id` and `TypeId`.
* Users can thus reuse the same `Id` to store many types.
* Uses a simple xor of id and typeid, which is fast and good since both id and typeid are already high-entropy hashes.
* Use different suffixes on the functions to pick if you want the data persisted or not (`get_temp`, `insert_persisted`, etc).
* Writing with one suffix and reading with the other works.
* To store state not bound to a specific `Id` (i.e. only based on type), use the new `Id::null` as the key.
* 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
* Make egui_glow and opt-in backend for eframe
* Add egui_glow to Cargo.toml and to CI
* Reference egui_glow where egui_glium is mentioned
* Remove path-patches from root Cargo.toml
* Add instructions on how to enable the glow backend of eframe
* implement stick-to-end scroll
* improve comment grammar
* accept emilk suggestion for demo text tweak
