- remove ScEd hacks and CFont et al macro rename - fix accursed bug in VFS buffer management that was causing ReadFile to fail without error (not allocating enough padding) - vfs_tree: bugfix in tree_lookup - waio: temporarily disable sector size determination (pending better approach - need to determine if using DVD drive) This was SVN commit r3421.
