Subject: mp4: Use automatic numbering for atom enum.
X-Git-Tag: v0.7.1~7^2~33
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=18ea2d87153bfcf386905b7c36b425d8e7bcc592;p=paraslash.git

mp4: Use automatic numbering for atom enum.

The exact numbers numbers of the ATOM enum are irrelevant. The only
thing which matters is the distinction between atoms we are only
interested in because they contain subatoms we care about and atoms
for which there is a corresponding read_xxx() parser.
