• [Frame header][FrameHeader].
• Table of contents (TOC).
• Actual frame data, in the following order, potentially permuted as specified in the TOC:
  • one LfGlobal,
  • num_lf_groups LfGroup's, in raster order,
  • one HfGlobal, potentially empty for Modular frames, and
  • num_passes times num_groups pass groups, in raster order.
