bg_tetra.png has a higher transparency because the feaures section wasn't very readable otherwise. Check again which transparency setting is best - should ideally be consistent across all backgrounds.
Decided to fade backgrounds even more - opacity is at 20% for all backgrounds.
Thus, consistency across all sections as required.
