  History:
  Yar - 19/06/11 - Fixed names of entry points in Windows (thanks to Johannes Pretorius, Bugtracker ID = 3319369)
  DaStr - 07/11/09 - Added $I GLScene.inc for Delhi 5 compatibility
  Improved FPC compatibility (thanks Predator) (BugtrackerID = 2893580)

  NOTE: For the demos to run you must have either fmod.dll (in Windows)
  or libfmod-3.75.so (in Linux) installed.

  In Windows, copy the fmod.dll file found in the api directory to either of
  the following locations (in order of preference)
  - your application directory
  - Windows\System (95/98) or WinNT\System32 (NT/2000/XP)

  In Linux, make sure you are signed in as root and copy the libfmod-3.75.so
  file from the api directory to your /usr/lib/ directory.
  Then via a command line, navigate to the /usr/lib/ directory and create
  a symbolic link between libfmod-3.75.so and libfmod.so. This is done with
  the following command (assuming you are in /usr/lib/)...
  ln -s libfmod-3.75.so libfmod.so.

    global mixed output of FMOD's software channels.

    it will return a unique handle for each FX.
    - FSOUND_FX_Enable cannot be called if the sound is playing or locked.

    if this happens.
