+    23) How do applications detect when the new texture layouts
+        corresponding to the image layouts in VK_KHR_maintenance2 are
+        supported in OpenGL?
+
+        RESOLVED: OpenGL contexts that report the GL_EXT_semaphore extension
+        string and have a DRIVER_UUID_EXT and DEVICE_UUID_EXT corresponding
+        to a Vulkan driver that supports VK_KHR_maintenance2 must support
+        the new OpenGL texture layouts.

 Revision History
 
+    Revision 13, 2017-09-26 (James Jones)
+        - Added new image layouts corresponding to those from
+          VK_KHR_maintenance2.
+        - Added issue 23 and resolution.
+
     Revision 12, 2017-06-08 (Andres Rodriguez)
         - Fixed parameter name in MemoryObjectParameterivEXT's description.
         - Fixed missing EXT suffix in some mentions of GetUnsignedByte*

+   174. OpenGL ES normally does not use or require double-precision
+        floating-point. Does the OpenGL ES version of this extension support
+        the double-precision entry points MatrixLoaddEXT, etc.)?
+
+        RESOLVED: Yes. This is an conscious choice, and only
