Crate surfman

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.
