     28 Overview
     29 
     30     Mesa is often used as a client library with no integration with
     31     the computer's window system (an X server, for example).  And since
     32     Mesa does not have an event loop nor window system callbacks, it
     33     cannot properly respond to window system events.  In particular,
     34     Mesa cannot automatically detect when a window has been resized.
     35 
     36     Mesa's glViewport command queries the current window size and updates
     37     its internal data structors accordingly.  This normally works fine
     38     since most applications call glViewport in responce to window size
     39     changes.
     40 
     41     In some situations, however, the application may not call glViewport
     42     when a window size changes but would still like Mesa to adjust to
     43     the new window size.  This extension exports a new function to solve
     44     this problem.

     55 
     56     The glResizeBuffersMESA command may be called when the client
     57     determines that a window has been resized.  Calling
     58     glResizeBuffersMESA causes Mesa to query the current window size
     59     and adjust its internal data structures.  This may include
     60     reallocating depth, stencil, alpha and accumulation buffers.
