Using the startMainLoop function and LoadingBar class

The optional debug mode bar on the top shows a log of render/update frames the main loop has processed.

• Green lines are updates which were rendered to the screen.
• Orange lines are updates which were not rendered to the screen.
• White lines are frames on which the game state was not updated.

Press f to fast-forward time in the debug mode.
