WEBGL_debug_renderer_info is deprecated in Firefox and will be removed. Please use RENDERER.

This snippet makes Firefox give the warning in the title:

glow/src/web_sys.rs

Lines 218 to 221 in 7e702f6

	webgl_debug_renderer_info: get_extension::<web_sys::WebglDebugRendererInfo>(
	&$context,
	"WEBGL_debug_renderer_info",
	),

I'm not sure about how glow uses that information (if it does at all), but it looks like you can use ctx.getParameter(ctx.RENDERER) to get something similar:

Question is, does this actually affect anything? What is this extension used for?

EDIT: In this crate, it isn't used at all. And this crate just provides those extensions for others to use. So this crate cannot actually do anything about that. So this warning should resolve itself once Firefox actually does deactivate that extension.

For example, egui_glow is already aware of this warning and produces it on purpose because there's no real way around it.

So I think this issue is not actually related to this crate and can be closed.
