Chris Dalton e278e1c1c7 Add an implementation and log2 variants for Wang's formula
Wang's formulas for cubics and quadratics (1985) tell us how many line
segments a curve must be chopped into when tessellating. This CL adds
an implementation along with optimized log2 variants, as well as tests
and a benchmark.
