OpenGL Overload: Implementing OpenGL Over Vulkan

VULKAN --
While some have long talked about trying to implement OpenGL over Vulkan drivers, we're finally seeing real work in this direction with the "OpenGL Overload" project.

OpenGL Overload aims to be a cross-platform OpenGL implementation atop Vulkan. The GitHub project page explains:
OpenGL Overload (GLO) aims at being a cross-platform implementation of OpenGL and building a streamline and modern APIs friendly OpenGL like API.

While Vulkan is a great explict graphics API, it's effortable only for a small part of the ecosystem. Furthermore, the multiplication of proprietary graphics APIs has fragmented the ecosystem.

Ideally this project will provide two front-ends: OpenGL and a modernized version OpenGL and multiple back-ends: Vulkan, Metal and DirectX12.

The amount of work needed is phenomenal, so let's see where it goes!
The code for it was just uploaded yesterday to GitHub. Before writing it off as a pipe-dream or something from an inexperienced over-optimistic developer, this project is being developed behind the developer of G-Truc.net, for those into OpenGL that may be familiar with G-Truc's GL samples, OpenGL reviews, and more. With that said, it will be very interesting to monitor this project and how it advances over the weeks/months ahead.
