# DL animation format
# XXX - collision with most `mips' magic
#
# I couldn't find a real magic number for these, however, this
# -appears- to work. Note that it might catch other files, too, so be
# careful!
#
# Note that title and author appear in the two 20-byte chunks
# at decimal offsets 2 and 22, respectively, but they are XOR'ed with
# 255 (hex FF)! The DL format is really bad.
#
#0 byte 1 DL version 1, medium format (160x100, 4 images/screen)
#>42 byte x - %d screens,
#>43 byte x %d commands
#0 byte 2 DL version 2
#>1 byte 1 - large format (320x200,1 image/screen),
#>1 byte 2 - medium format (160x100,4 images/screen),
#>1 byte >2 - unknown format,
#>42 byte x %d screens,
#>43 byte x %d commands
# Based on empirical evidence, DL version 3 have several nulls following the
# \003. Most of them start with non-null values at hex offset 0x34 or so.
#0 string \3\0\0\0\0\0\0\0\0\0\0\0 DL version 3
# SGI and Apple formats
0 string MOVI Silicon Graphics movie file
4 string moov Apple QuickTime movie file (moov)
4 string mdat Apple QuickTime movie file (mdat)
