Texture coordinates are stored in fixed point format in TEV which allows overflows to be emulated correctly. Added logic to calculated texture LOD and use the correct mip. Dumping textures will now dump all mip levels. Added line rendering. Changed data stored in vertex from float arrays to vectors for cleaner math.
