minimize the GLSL code?

[gre]

we should also export to NPM glsl minified version of the code that we would use for "prod", it needs to be tested the same way it is with the non minified and it also needs to be used by everything (except the gl-transitions editor).

I think it will just be another entry point with a .min suffix in the filename.

gl-transitions.min.json, gl-transitions.min.js,...
but also the lib index.js probably should be the min by default and there are non min versions?
