Keep state variable to enumerate things. This allows us to remove the expectation that the same index will give the same item. Use a new rectangle type for video size. When enumerating sizes, this allows us to specify relations between width and height more easily. Remove the struct and bytes type, they are like pointer. Add filter to enum_formats to speed up enumerations.
