* 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
* Re-add check of WEBGL_debug_renderer_info to avoid OpenGL error
I removed this check in https://github.com/emilk/egui/pull/1020
because it produced a warning on Firefox. Better a warning
than an OpenGL error though.
* Bug fix: don't ask for webgl context and then later for webgl2 context
The browser will only allow the first thing we check, so this will
prevent webgl2 from working.
* Allow setting the scale filter for `glow` backend
This commit adds a `set_scale_filter` method to the `glow` painter so that
textures can be set to scale using nearest-neighbour scaling rather than
linear. This is useful for pixel art.
I wasn't entirely sure what kind of API you want for this kind of change so I
went with what seemed least intrusive, I don't mind doing something more
holistic if this isn't what you had in mind.
* Rename scale_filter -> texture_filter
* Store the TextureFilter directly
* PR link in changelog
* Use inter-doc links
