##// END OF EJS Templates
Removed the timer callback in favor of the idle one and re-use wx waiting time after an event is processed. This make things more reactive. Also, the created window is now made insivisible and is not supposed to be ever show or detroyed. Finally, fixed the bug in window closing for linux platform using the glutSetOption available on Freeglut.
