- color: the sse codepath is now detected and activated from within color.cpp, which avoids making ia32 dependent on the color header. it's called from gamesetup!InitRenderer. - move VFSUtil::EnumDirEnts to vfs.cpp!vfs_dir_enum - allows it to be used from within lib/ without dependency on ps (annoying for other projects) This was SVN commit r3764.
