Description

Galaxie Event Loop is a low tech main loop couple with a event bus.

After many years as kernel of Galaxie Curses project, it have been as decision to extract the main loop and the event bus. Especially that because it work and be very small.

It Take 2 iterations for the loop to slow FPS for match the 30 FPS ask by the setting. The mainloop can impose a Frame Rate :)
