If we can confirm that this works - yes, possibly. Or I'll put the math into engine.
I'm still a bit confused why representing 1/3 in floats hasn't become a problem yet. Half-speculating that the driver might actually optimize out the divisor when realizing that the surface has a size divisible by 3 or something...
Edit: Just checked - the GLSL 1.10 specs (7 years old!) already states that:
This should be completely legal...
