Native bindings to the EXT_device_openwf 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.

These extensions define how to map device and output handles between EGL and OpenWF Display. An EGL implementation which provides these extensions must have access to sufficient knowledge of the OpenWF implementation to be able to perform these mappings. No requirements are imposed on how this information is obtained, nor does this support have any implications for how EGL devices and outputs are implemented. An implementation which supports these extensions may support other low level device interfaces, such as DRM/KMS, as well.

Requires EXT_device_base.
