comparison data/fileio/OggVorbisFileReader.cpp @ 1359:1c9bbbb6116a 3.0-integration

Use W64 instead of WAV for decoded files; use Ogg reader in preference to WAV one for Ogg files (WAV reader works, via libsndfile, but doesn't load metadata); fix Ogg reader to use QFile open instead of non-Win32-compatible API; add more encoder tests, audio writer test, midi reader test
