Detailed Description

FLI/FLC file demuxer by Mike Melanson (melan.nosp@m.son@.nosp@m.pcisy.nosp@m.s.ne.nosp@m.t) for more information on the .fli/.flc file format and all of its many variations, visit: http://www.compuphase.com/flic.htm.

This demuxer handles standard 0xAF11- and 0xAF12-type FLIs. It also handles special FLIs from the PC games "Magic Carpet" and "X-COM: Terror from the Deep".
