* 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.
* 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

* 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
