through stream that translates glsl-parser AST nodes into working glsl code

, parser = require('glsl-parser')
, deparser = require('glsl-deparser')
process.stdin
.pipe(tokenizer)
.pipe(parser())
.pipe(deparser()) // <-- deparser!
.pipe(process.stdout)

`
transform a stream of glsl-parser AST nodes
into strings.
only operates on top-level statements emitted by glsl-parser, so the code it emits is executable
by webgl.
Creates a readable/writable stream.
If no args are provided, whitespace is assumed to be enabled, and the tab text will be ' '.
If you pass false for the first arg, only syntactically significant whitespace will be emitted (it'll behave like a poor man's minifier).
If you pass true and tab text, that tab text will be used to indent code.
the big caveat is that preprocessor if statements (#if*, #endif`) won't work unless
each branch produces a parseable tree.
