			Performs a buffer swap on the layer in use for the current window. Specifically, <tt>glutSwapBuffers</tt>
			promotes the contents of the back buffer of the layer in use of the current window to become the contents of the front
			buffer. The contents of the back buffer then become undefined. The update typically takes place during the vertical
			retrace of the monitor, rather than immediately after <tt>glutSwapBuffers</tt> is called.
		</p><p>
			An implicit <a href="glFlush.3G.xml"><tt>glFlush</tt></a> is done by <tt>glutSwapBuffers</tt> before it
			returns. Subsequent OpenGL commands can be issued immediately after calling <tt>glutSwapBuffers</tt>, but
			are not executed until the buffer exchange is completed.
		</p><p>
			If the layer in use is not double buffered, <tt>glutSwapBuffers</tt> has no effect.
