This extension allows an application to specify a minimum periodicity
of color buffer swaps, measured in video frame periods.
+Issues
+
+ * Should implementations that export GLX_MESA_swap_control also export
+ GL_EXT_swap_control for compatibility with WGL_EXT_swap_control?
+
+ UNRESOLVED.

New Procedures and Functions
int glXSwapIntervalMESA(int interval)
The swap interval is not part of the render context state. It cannot
be pushed or popped. The current swap interval for the window
associated with the current context can be obtained by calling
- glXGetSwapIntervalMESA. The default swap interval is 1.
+ glXGetSwapIntervalMESA. The default swap interval is 0.
- On XFree86, setting the environment variable LIBGL_NO_VSYNC sets the
- swap interval to 0.
+ On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
+ the swap interval to 1.
