Opt-in earlier-game support. [SKPROJECT]'s SKWINSPX/src/v5/bgdat.cpp allow-lists graphics signatures 2/4/5 and rejects 3/1. Format 2 (0x8002) is read by its v6 DM1-mode extension; format 1 (0x8001) is the DOS-LE pre-DM2 / DM/CSB sentinel; format 3 (0x8003) is unwitnessed in any known source - likely reserved but never shipped, confirm or refute. Growth in dm2-graphics/dm2-dungeon for DM1 / Chaos Strikes Back / Theron's Quest / Bloodwych. See docs/formats/graphics-dat.md.
