◆ FMT_VER

enum class ALLEGRO::FMT_VER

strong

The format of an Allego file.

Allgro formats seem to be versioned per the magic, with the lowest byte masked out (or at least there no known case of the lower magic byte changing the format.

But the version does not seem to be directly related to the Allegro version (e.g. 17.2) itself.
