-    Mesa 2.2 or later is required.
-
-Overview
-
-    Mesa is often used as a client library with no integration with
-    the computer's window system (an X server, for example).  And since
-    Mesa does not have an event loop nor window system callbacks, it
-    cannot properly respond to window system events.  In particular,
-    Mesa cannot automatically detect when a window has been resized.
-
-    Mesa's glViewport command queries the current window size and updates
-    its internal data structors accordingly.  This normally works fine
-    since most applications call glViewport in response to window size
-    changes.
-
-    In some situations, however, the application may not call glViewport
-    when a window size changes but would still like Mesa to adjust to
-    the new window size.  This extension exports a new function to solve
-    this problem.
-
-New Procedures and Functions
-
-    void glResizeBuffersMESA( void )
-
-New Tokens
-
-    none
-
-Additions to the OpenGL Specification (no particular section)
-
-    The glResizeBuffersMESA command may be called when the client
-    determines that a window has been resized.  Calling
-    glResizeBuffersMESA causes Mesa to query the current window size
-    and adjust its internal data structures.  This may include
-    reallocating depth, stencil, alpha and accumulation buffers.
-
-Additions to the AGL/GLX/WGL Specifications
-
-    None
-
-Errors
-
-    INVALID_OPERATION is generated if glResizeBuffersMESA is called between
-    Begin and End.
-
-New State
-
-    None.
-
-New Implementation Dependent State
-
-    None.
