    Class IndirectBuffer

    Utility to handle indirect drawing.

    Create a buffer, fill it with all the added geometries attributes and tell all the geometries to start using this buffer for indirect drawing.

    const geometry = new Geometry()

    // assuming 'renderer' is a valid renderer or curtains instance
    const indirectBuffer = new IndirectBuffer(renderer, {
      label: 'Custom indirect buffer',
      geometries: [geometry]
    })

    // if every geometries have been added, create the buffer.
    indirectBuffer.create()

    // from now on, any Mesh using 'geometry' as geometry will be rendered using indirect drawing.
