Realistically, are there going to be competing standard aspect ratios 
within epsilon?

For hardware that can do flexible ratios, is double-precision 
insufficient to deduce the other pixel dimension?

If not, then I think this is largely a problem that implementations 
should solve without affecting users. Users specifying 1.78, 
1.77777777778 or 16/9 presumably all mean exactly the same thing, the 
standard 16:9 widescreen aspect. Thus an epsilon seems reasonable to me 
for aspectRatio, and introducing fractions seems overkill from a user's 
perspective.
