Update of /cvsroot/scummvm/scummvm/saga
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv10963

Modified Files:
	actor.cpp font.cpp game.cpp game.h game_mod.h interface.cpp 
	music.cpp music.h rscfile.cpp rscfile_mod.h saga.cpp scene.cpp 
	script.cpp sndres.cpp sndres.h sound.cpp sound.h sprite.cpp 
Log Message:
o Make GAME_GetFileContext() more object-like
o Font::loadFont() now normally survives zero-length fonts as used in demos
o Removed unused SndRes::ITEVOC_Resample()
o Fixed playing of voice #4 on old DOS targets
o Implemented playing voices in VOX (Oki ADPCM) format
o Support of Win32 and Linux demos. There was old-style Win32 demo, which
  is not supported yet, same is with DOS demo.
