Wad files are used for scenario data, images such as those in terminals and the
main menu, and physics files. Here is a listing of all chunks used within them:

Map files can be identified by the `Minf` chunk.
Maps will always have either a `PNTS` or `EPNT` chunk, depending on what the
map (and editor) use. `PNTS` are plain and have no more information than the
actual position, while `EPNT` can be loaded directly into memory by the engine.
`EPNT` also tells the engine that the map is preprocessed and that `iidx` and
`PLAT` chunks also exist.
Physics tags:

| `FXpx` | Array of Effect Definition |
| `MNpx` | Array of Monster Definition |
| `PRpx` | Array of Projectile Definition |
| `PXpx` | Array of Physics Definition |
| `WPpx` | Array of Weapon Definition |
Physics definitions may be embedded into a map in Infinity and Aleph One, so
the only reliable way to check if something is a pure physics file is by
checking that there are no chunks other than `**px` chunks.

Map files can be identified by the Minf chunk.

the actual position, while `EPNT` can be loaded directly into memory by the

Images can be identified by the PICT chunk.
Physics definitions may be embedded into a map, so the only reliable way to
check if something is a pure physics file is by checking that there are no
chunks other than `XXpx` chunks.
The file extensions used for Wad files include `imgA` for `Images`, `sceA` for
`Map`, and `phyA` for `Physics`.
