// SetSwapInterval selects the minimum number of monitor vertical retraces that
// should occur between two buffer swaps. If the selected swap interval is one,
// the rate of buffer swaps will never be higher than the vertical refresh rate
// of the monitor. If the selected swap interval is zero, the rate of buffer
// swaps is only limited by the speed of the software and the hardware.

// SwapInterval sets the swap interval for the current context, i.e. the number
// of screen updates to wait before swapping the buffers of a window and
// returning from SwapBuffers. This is sometimes called
// 'vertical synchronization', 'vertical retrace synchronization' or 'vsync'.
//
// Contexts that support either of the WGL_EXT_swap_control_tear and
// GLX_EXT_swap_control_tear extensions also accept negative swap intervals,
// which allow the driver to swap even if a frame arrives a little bit late.
// You can check for the presence of these extensions using
// ExtensionSupported. For more information about swap tearing,
// see the extension specifications.
//
// Some GPU drivers do not honor the requested swap interval, either because of
// user settings that override the request or due to bugs in the driver.
