// to using the screen refresh rate to compute the elapsed time.
// If V-sync is not enabled, using the screen refresh rate is plain wrong
// (the refreshTimer period would be ok though).
// If frames are dropped, it is mandatory to refer to a timer to be correct.
// We rasterized the elapsed value to the theorical value
// (based on the screen frequency) in order to keep a
// constant value in most of the case.
// Ex: given a 60Hz screen refresh rate
// - 400 ticks / 16.6ms in normal case
// - 0 ticks / 0ms if VSYNC is not enabled and the timer
// - a multiple of 400 ticks / 16.6ms if frame were dropped
