Experiment rational trigonometry optimizations

[LifeIsStrange]

https://en.m.wikipedia.org/wiki/Rational_trigonometry

I wonder if the finitist framework of rational trigonometry could allow some new optimizations.
More information at the wiki section "Computation – complexity and efficiency"

I don't have much knowledge about the subject but I (naively) wonder if it could be useful to webrender.
Otherwise, feel free to close the issue!
