Game, Simulation, etc: Separated 'update' and 'interpolate', and made 'update' return whether it's going fast enough (so callers can decide to do more updates per render). Changed some time variables to 'double' so they have enough precision in long games. Atlas: Added "Fast" playback button. Made simulation sometimes go at real-time speed, if it's just slightly too slow at rendering. VertexBuffer: Removed some non-useful glGetError calls. Entity: Commented out redundant Tick code. Fixed syntax error in disabled code that confused the IDE. Aura: Changed string code again, to simply use ASCII instead of UTF-16. (SpiderMonkey seems to handle it just as efficiently, for small strings.) Misc: Some more minor header-file cleanup. SVN log: Added feed link. This was SVN commit r4807.
