// - Gather vertex data from face start index + length
// - Store vertex data in scratchpad memory (should be plenty of space for one face)
// - Perform camera offset and re-scaling operations to fit vertex data in signed 16-bit fixed point vectors
//   - Note: may be possible to (ab)use 32-bit GTE registers & ops to do this calculation and downcast
// - Store rescaled vertex data in scratchpad memory
