Would it make sense to remove the renderer which uses the deprecated gfx crate?

https://github.com/gfx-rs/gfx#the-gfx-crate

This repository was originally home to the gfx crate, which is now deprecated. You can find the latest versions of the code for that crate in the pre-ll branch of this repository.

and the last release of gfx (0.18.2) was close to a year ago and is presumably the final release

The reason it might be worth removing is it is maybe (at least it was to me) a little confusing as the gfx repo is still active, but it is now being used for the gfx-hal package. So I initially assumed the imgui-gfx-renderer was as-valid a thing to use for a new project as glium. To add further confusion, the gllium repo says it is "no longer actively developed by its original author" (which on first glance reads like the project is dead, but it's actually just maintained by different people - edit: made issue about clarifying this with glium project here)

I can see the value in having more than one example integration codebase - which is probably where #243 comes in I guess!
