Struct CompatGl 

pub struct CompatGl { /* private fields */ }

GLES2-era drawing symbols for simple compatibility rendering.

This is narrower than glsym::init(): it deliberately avoids product renderer symbols such as scissor, draw-elements, matrices, texture arrays, VAOs, instancing, and blend equations.
