1-bit TIFFs compressed with CCITT Group 3 did not open, place or relink: the image decoder reads Group 4 only and refuses Compression 2 (modified Huffman) and Compression 3 (ITU-T T.4). They are now decoded with hayro-ccitt, the CCITT decoder that EPS import uses. Compression 2 rows start at a byte and have no EOL codes. Compression 3 rows follow an EOL code and are one-dimensional, or, with T4Options bit 0, one- or two-dimensional as each row's tag bit says. Fill bits, FillOrder 2, either PhotometricInterpretation, strips and tiles are read. A file whose pixels would take more than the decoding allowance as RGBA is refused as too large to draw. A strip or tile whose data ends before its last row is refused as damaged, and so is a tile larger than the allowance. The strips and tiles together are read from at most as many bytes as the file holds. Part of #1466. Docs: docs/file-format-parity.md, docs/target-app-parity.md.
