Debug mode

requirebin seems to use browserify without --debug, it would be nice if requirebin turned debug mode on.

Example using regl (working requirebin):

const quad = require('glsl-quad');
const regl = require('regl')();

let frag = `
    THIS IS AN OBVIOUSLY BAD SHADER.

  IT SHOULD THROW AN ERROR.

  BUT REGL ONLY THROWS AN ERROR IN DEBUG MODE.

  WHICH MEANS WE WILL ONLY SEE A WARNING. (CHECK
  THE CONSOLE).

             CAN WE GET REQUIREBIN
              TO USE DEBUG MODE?
`;

let draw = regl({
  vert: quad.shader.vert,
  frag: frag,
  attributes: {
    a_position: quad.verts,
    a_uv: quad.uvs
  },
  elements: quad.indices,
  uniforms: {
    u_clip_y: 1
  }
});

draw();

The issue identifies requirebin's Browserify invocation but names no file or test. Locate where Browserify is configured, check how its debug option is passed, and use the linked regl example to verify that the shader failure produces the expected debug error rather than only a warning.
