| // This test came about as the result of bug #1262773 |
| // |
| // It closes and re-opens the GLFW window every five seconds, alternating |
| // between windowed and fullscreen mode |
| // |
| // It also times and logs opening and closing actions and attempts to separate |
| // user initiated window closing from its own |
