qzdoom-gpl/src/s_environment.cpp
Randy Heit 4a1cb412f1 - Add environment 255, 255 as a way to get the software underwater effect in
any zone you want.
- Using a too-recent version of FMOD now gives an error, since there may be
  breaking changes to the API from one version to the next (excluding
  revisions in stable branches, which only represent bug fixes).
- Updated fmod_wrap.h for FMOD 4.16 and corrected a bug that had gone
  unnoticed before: The delayhi and delaylo parameters for Channel::setDelay()
  and getDelay() were swapped.
