Struct luminance_gl::gl33::GLState

pub struct GLState { /* private fields */ }

The graphics state.

This type represents the current state of a given graphics context. It acts as a forward-gate to all the exposed features from the low-level API but adds a small cache layer over it to prevent from issuing the same API call (with the same parameters).
