The .bmfc is the Liberation Sans 16px one with the font name and file changed, and an angle mark cut to fit the cell.
Every glyph advances by the same 8px.  Sheets are made with ..\BMFont and regenerated with ..\MakeFonts.py, as described in
..\LiberationSans\README.  The .ttf is packed to keep the tree small, and MakeFonts.py unpacks it under Junk\Fonts.
