    // data (i.e. a byte of red, followed by a byte of green...).  While the Bitmap
    // constructor that takes an int[] wants little-endian ARGB (blue/red swapped), the
    // Bitmap "copy pixels" method wants the same format GL provides.
    //
    // Ideally we'd have some way to re-use the ByteBuffer, especially if we're calling
    // here often.
    //
    // Making this even more interesting is the upside-down nature of GL, which means
    // our output will look upside down relative to what appears on screen if the
    // typical GL conventions are used.
