// @description More accurate implicit functions in Desmos! Very slow if you crank it up high. Incompatible with other userscripts that change workers.

/*
To change resolution, change the exponent on Math.pow(2,18).
I'm estimating that higher than 22 would crash most computers when plotting a single implicit graph.
The default value is 14.
