[1:16:53][@waterlimon][Is 'real32' ambiguous because it could be either floating point or fixed point?]
[1:17:45][@krohnos][Is the non-smooth movement at higher zoom levels due to not being optimized or some sort of issue with sub-pixel smoothness?]
[1:18:06][@davidthomas426][Would it look different if you scale WidthOfMonitor and FocalLength together, constrained to the same ratio?]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.
