Sorry that was the wrong dire
So how do you actually build the parser? I downloaded the source but I don’t
see a binary.

I think they added const. In the past I’ve seen using “let” but I don’t think
that’s a real const if that

Yeah I mistyped. We shouldn’t be redefining GLfloat though (I doubt it’s a
double in OpenGLES/WebGL either) so how does this (or other types) translate
for the parser?
