//! Cross-platform GPU device and surface management.
//!
//! You can use this crate to multithread a graphics application so that rendering happens on
//! multiple threads, sharing textures among them in the most efficient manner. It may also be
//! useful as a lightweight framework for *just* initializing rendering in native applications.
//! This is in contrast to crates like SDL, GLFW, winit, and Glutin, all of which have a broader
//! focus in that they manage windowing and the event loop as well.
