Write gfx-hal backend for Turbine-Scene3D

[bvssvni]

Currently, it only uses OpenGL.

This sounds fun to implement, will this depend on a Piston gfx-hal_graphics repo of some sort that doesn't exist yet?

https://github.com/amethyst/rendy could probably save you a lot of work here.

I would love to see Rendy being used here.

@aaruel @bvssvni if you’re on Discord the best way to get this moving would be to come by our https://Discord.gg/Amethyst #rendering channel. Otherwise you can try to ping @omni-viral, @Frizi & @termhn with specific implementation questions here.
