  Refactor how we store vertex formats.
  
  Instead of storing a vertex format as a struct with the full info,
  instead use an enum, and look up the info when we need it. This
  saves a lot of constructor initialization time, operator comparison
  time, and storage. It also will allow us to look up D3D format info
  more quickly.
