789210fa22 Almost from scratch rewrite of filter parser. 
Functional as is, but still work-in-progress in the
sense that some things need to be fixed before sending
it as a patch to SVN.

including auto-inserted scale filters.  As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.

improve the link configuration process, to be committed next.

b3ab2f7e84 Add another "reuse" permission, to distinguish between the case where a 
source filter will simply want to re-output the same image multiple times
and reuse a buffer to do it, and the case where the source filter will
output multiple image by modifying a single buffer and outputting it multiple
times.

cc0bb5a160 Change the passthrough filter to a noformat filter. It's now similar to 
the mplayer noformat filter except that the default behavior if no formats
are specified is to allow allow all formats (ie. virtually the same as the
old passthrough behavior)

698181056d Rework link property configuration system. 
This can now handle filters which are added to graphs out of order,
including auto-inserted scale filters.  As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.
