- * Calculate amount of swap interval used between GLX buffer swaps.
- *
- * The usage value, on the range [0,max], is the fraction of total swap
- * interval time used between GLX buffer swaps is calculated.
- *
- * \f$p = t_d / (i * t_r)\f$
- *
- * Where \f$t_d\f$ is the time since the last GLX buffer swap, \f$i\f$ is the
- * swap interval (as set by \c glXSwapIntervalSGI), and \f$t_r\f$ time
- * required for a single vertical refresh period (as returned by \c
- * glXGetMscRateOML).
- *
- * See the documentation for the GLX_MESA_swap_frame_usage extension for more
- * details.
- *
- * \param dPriv Pointer to the private drawable structure.
- * \return If less than a single swap interval time period was required
- * between GLX buffer swaps, a number greater than 0 and less than
- * 1.0 is returned. If exactly one swap interval time period is
- * required, 1.0 is returned, and if more than one is required then
- * a number greater than 1.0 will be returned.
- *
- * \sa glXSwapIntervalSGI glXGetMscRateOML
- *
- * \todo Instead of caching the \c glXGetMscRateOML function pointer, would it
- * be possible to cache the sync rate?
