 Overview
 
     This extension defines a way of sharing texture image data between texture
     objects in different contexts where the contexts would not normally share
-    texture resources. Three new functions are exported. glGenMailboxCHROMIUM
+    texture resources. Five new functions are exported. glGenMailboxCHROMIUM
     generates a name that can be used to identify texture image data outside
-    the scope of a context group. glProduceMailboxCHROMIUM associates a texture
-    object with a global mailbox name. glConsumeMailboxCHROMIUM associates the
-    texture object referenced by a mailbox name to a texture name.
+    the scope of a context group. glProduceMailboxCHROMIUM and 
+    glProduceTextureDirectCHROMIUM associate a texture object with a global
+    mailbox name. glConsumeMailboxCHROMIUM and glCreateAndConsumeTextureCHROMIUM
+    associate the texture object referenced by a mailbox name to a texture name.
 
 New Procedures and Functions
 
     void glGenMailboxCHROMIUM (GLbyte *mailbox)
 
     Generates a unique name identifying a mailbox. The name is generated using
     a cryptographic random number generator and is intended to be difficult to
     guess. The scope of the name is implementation specific, for example it
     might not span multiple displays.
