57 * We read source bytes into get_buffer and dole out bits as needed.
58 * If get_buffer already contains enough bits, they are fetched in-line
60 * bits, jpeg_fill_bit_buffer is called; it will attempt to fill get_buffer
64 * On TRUE return, jpeg_fill_bit_buffer guarantees that get_buffer contains
