Native bindings to the EXT_output_base extension.

Increasingly, EGL and its client APIs are being used in place of "native" rendering APIs to implement the basic graphics functionality of native windowing systems. This creates demand for a method to initialize EGL displays and surfaces directly on top of native GPU or device objects rather than native window system objects. The mechanics of enumerating the underlying native devices and constructing EGL displays and surfaces from them have been solved in various platform and implementation- specific ways. The EGL device family of extensions offers a standardized framework for bootstrapping EGL without the use of any underlying "native" APIs or functionality.

This extension defines new EGL resource types for referencing display control hardware associated with an EGL device. Its purpose is to allow rendering to be directed to a screen in the absence of (or bypassing) a window system. Because the use models for these resources are potentially diverse, only the objects themselves and basic functions to acquire and query them are defined here. More detailed functions and enumerants required to operate on outputs are provided by separate extensions.

Requires EXT_device_base.
