nuclear@14 108 NOTES:
nuclear@14 109 * Name chunks are mandatory. If something doesn't have a name, one must be made
nuclear@14 110 up, even if it's just "object%d".
nuclear@14 111 * In node chunks, both POS/ROT/SCALE, and MATRIX0/MATRIX1/MATRIX2 are mandatory
nuclear@14 112 and they must agree. Makes it easy for the reader to pick the transformation
nuclear@14 113 data in whichever way is more convenient.
