docs: Creates buffers from typed arrays
  
  Given something like this
  
  var arrays = {
  positions: [1, 2, 3],
  normals: [0, 0, 1],
  }
  
  returns something like
  
  buffers = {
  positions: WebGLBuffer,
  normals: WebGLBuffer,
  }
  
  If the buffer is named 'indices' it will be made an ELEMENT_ARRAY_BUFFER.
  
  @param {WebGLRenderingContext} gl A WebGLRenderingContext.
  @param {Object<string, array|typedarray>} arrays
  @return {Object<string, WebGLBuffer>} returns an object with one WebGLBuffer per array
