The Khronos Group has also released their ratified specification for EGL 1.5. This API is at the center of data and event management between other Khronos APIs. This version increases security, interoperability between APIs, and support for many operating systems, including Android and 64-bit Linux.
The headline on the list of changes is the move that EGLImage objects makes, from the realm of extension into EGL 1.5's core functionality, giving developers a reliable method of transferring textures and renderbuffers between graphics contexts and APIs. Second on the list is the increased security around creating a graphics context, primarily designed for WebGL applications which any arbitrary website can become. Further down the list is the EGLSync object which allows further partnership between OpenGL (and OpenGL ES) and OpenCL. The GPU may not need CPU involvement when scheduling between tasks on both APIs.
During the call, the representative also wanted to mention that developers have asked them to bring EGL back to Windows. While it has not happened yet, they have announced that it is a current target.
The EGL 1.5 spec is available at the Khronos website.
