// to avoid partially compressed output resulting in blank pages in
// the browser or error messages, compression is disabled in a few cases:
//
// 1) if headers have already been sent, this indicates plaintext output
// has been started so further content must not be compressed
// 2) the length of the current output buffer is non-zero. This means
// there is already some uncompressed content in this output buffer
// so further output must not be compressed
// 3) if more than one level of output buffering is used because we
// cannot test all output buffer level content lengths. One level
// could be caused by php.ini output_buffering. Anything
// beyond that is manual, so the code wrapping phpBB in output buffering
// can easily compress the output itself.
