Version Version 1, 2018-5-22 Number EGL Extension XXX Extension Type EGL Client Extension Dependencies OpenGL ES 3.1 is required. EGL_KHR_get_all_proc_addresses is required. EGL_EXT_client_extensions is required. Overview This extension adds new OpenGL ES entry points that allow the user to pass the current EGL context as a function parameter. This allows users to skip lookup of the thread's current context upon entry. New Types None. New Procedures and Functions For every OpenGL ES entry point available through eglGetProcAddress, an additional entry point is made available. The entry points have the form of: glContextANGLE(GLeglContextANGLE context, ) If a function already has an extension suffix, this form still applies. New Tokens None. Additions to the EGL Specification When using OpenGL ES as a client library, the ContextANGLE entry points allow the user to pass the current EGL context as a function parameter to provide better performance than looking up the current EGL context at every GL entry point. Calls made with an explicit context provide no additional validation for the passed context parameter. Calls made with an explicit context will generate errors under the same conditions as they would without an explicit context. Any instances of undefined behaviour without specifying an explicit context are still undefined when specifying an explicit context. When an EGL context that is not current is explicitly passed, the resulting behavior is undefined. Issues None. Revision History Version 1, 2018-5-22 (Brandon Jones) - Initial draft
