| '''OpenGL extension MESA.resize_buffers |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.MESA.resize_buffers to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| 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 responce 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. |
