Struct Gl 

pub struct Gl { /* private fields */ }

Ergonomic OpenGL access for libretro hardware-rendered cores.

Gl::init requires only the minimal symbols needed to submit a legal hardware-rendered frame. Shader, buffer, texture, blending, and richer GL entry points are loaded opportunistically so cores can keep a clear-only diagnostic path alive on frontends with incomplete symbol lookup.
