Testing out tree shaking a three.js app with rollup.
Not sure if I'm using rollup propery.

Rollup:
Bundle size: 545.26 KB, Gzipped size: 112.07 KB

Rollup + uglify:
Bundle size: 305.55 KB, Gzipped size: 75.17 KB

Rollup + Closure Compiler (SIMPLE):
Bundle size: 308.5 KB, Gzipped size: 75.77 KB

Rollup + Closure Compiler (ADVANCED):
Bundle size: 241.33 KB, Gzipped size: 63.7 KB
(shit load of compiler errors and doesn't work)

install: npm install
build: npm run build
