+
+    Based on GLX_SGI_swap_control version 1.9 and WGL_EXT_swap_control

+
+Overview
+
+    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.

+Additions to the GLX 1.3 Specification
+
+    [Add the following to Section 3.3.10 of the GLX Specification (Double
+     Buffering)]
+
+    glXSwapIntervalMESA specifies the minimum number of video frame periods
+    per buffer swap.  (e.g. a value of two means that the color buffers
+    will be swapped at most every other video frame.)  A return value
+    of zero indicates success; otherwise an error occurred.  The interval
+    takes effect when glXSwapBuffers is first called subsequent to the
+    glXSwapIntervalMESA call.
+
+    A video frame period is the time required by the monitor to display a 
+    full frame of video data.  In the case of an interlaced monitor,
+    this is typically the time required to display both the even and odd 
+    fields of a frame of video data.
+
+    If <interval> is set to a value of 0, buffer swaps are not synchro-
+    nized to a video frame.  The <interval> value is silently clamped to
+    the maximum implementation-dependent value supported before being
+    stored.
+
+    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 0.
+
+    On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
+    the swap interval to 1.
+
+Errors
+
+    glXSwapIntervalMESA returns GLX_BAD_CONTEXT if there is no current
+    GLXContext or if the current context is not a direct rendering context.
+
+GLX Protocol
+
+    None.  This extension only extends to direct rendering contexts.
