- * Mesa/X11 interface. This header file serves as the documentation for
- * the Mesa/X11 interface functions.
- *
- * Note: this interface isn't intended for user programs. It's primarily
- * just for implementing the pseudo-GLX interface.
- */
-
-
-/* Sample Usage:
-
-In addition to the usual X calls to select a visual, create a colormap
-and create a window, you must do the following to use the X/Mesa interface:
-
-1. Call XMesaCreateVisual() to make an XMesaVisual from an XVisualInfo.
-
-2. Call XMesaCreateContext() to create an X/Mesa rendering context, given
- the XMesaVisual.
-
-3. Call XMesaCreateWindowBuffer() to create an XMesaBuffer from an X window
- and XMesaVisual.
-
-4. Call XMesaMakeCurrent() to bind the XMesaBuffer to an XMesaContext and
- to make the context the current one.
-
-5. Make gl* calls to render your graphics.
-
-6. Use XMesaSwapBuffers() when double buffering to swap front/back buffers.
-
-7. Before the X window is destroyed, call XMesaDestroyBuffer().
-
-8. Before exiting, call XMesaDestroyVisual and XMesaDestroyContext.
