Only a tiny patch polishing the user interface:
- The left/right/esc icons have been moved slightly towards the centre to improve the layout for some aspect ratios (and the main text is a bit smaller to make space for them).
- The areas to click the left/right/esc icons now move with the icons. (Previously they were defined relative to the window).
- The bottom rod moves smaller distances for the credits such that it should stay inside the window for more aspect ratios.
As always, please let me know any comments!
