 Per discussion lead by Jean-Michel Pouré on macports-devel
 [http://lists.macosforge.org/pipermail/macports-
 dev/2009-January/007102.html]
 the attached patch sets default_variants to include all available optional
 codecs on the grounds that the spirit of the distribution is to provide
 support for conversion between as many different encodings as possible.

 This includes
 {{{
 +a52 +extvorbis +faac +faad +lame +theora +x264 +xvid
 }}}
 The following variants remain optional by default
 {{{
 +avfilter (experimental)
 +gpl (automatically included as necessary)
 +mmx (experimental/buggy)
 +postproc (experimental)
 }}}
 The revision is incremented to reflect the change in
 port functionality (for the better, IMHO)
