Summer Garden Custom Variation

By Whittaker Courtney

The same custom variation that made summer garden used here.
It's similar in behavior to the julia_outside function but acts differently and can do some cool stuff.

default formula = sin(acos(z+2)/2) + cos(acos(z-2)/2)

mode 0 default, mode 1 = swap sin and cos, mode 2 = square entire formula.
