-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

-New Tokens

-
-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.
