  Message : 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.
