+
+Number
+
+    OpenGL Extension #545
+
+Dependencies
+
+    EGL_KHR_fence_sync is required.
+
+    This extension is written against the EGL 1.2 Specification, as modified by
+    the EGL_KHR_fence_sync extension.
+
+Overview
+
+    This extension extends EGL_KHR_fence_sync with client API support for
+    OpenGL (compatibility or core profiles) as a Mesa extension.
+
+    The "GL_MESA_EGL_sync" string indicates that a fence sync object can be
+    created in association with a fence command placed in the command stream
+    of a bound OpenGL context.

+Additions to Chapter 3 of the EGL 1.2 Specification (EGL Functions and Errors)
+
+    Modify Section 3.8.1 Sync Objects, page 43
+
+    After "Each client API which supports..." add a new paragraph:
+
+    If the GL_MESA_EGL_sync extension is supported by OpenGL (compatibility or
+    core profile), a fence sync object may be created when the currently bound API
+    is OpenGL.

+Errors
