Marching.js combinators don't work in the latest version #102
Description
Run the following for example:
Union2(
Sphere(.5).translate(-1.5,0,0),
Sphere(.5).translate( 1.5,0,0)
).render()
The console shows errors indicating that the shader failed to compile: INVALID_OPERATION: program not linked
After that nothing renders and the whole visual environment seizes to work.
The same thing happens trying to use all combinators as far as I can tell: Difference, Intersection... All the primitives like Sphere().render() do work fine though.
The same errors are observed when running it locally after cloning, in https://gibber.cc/playground/ and in https://gibber.cc/alpha/playground/.
These combinators do work fine over at https://charlieroberts.github.io/marching/playground/, so it's not an issue of marching.js with modern browsers, it's an issue with bundling it within Gibber.
