459821c533 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.

4d62c9d377 Track the permissions that have been given out to each picture. 
This should make it easier to know what can be done to a buffer once
it's been passed to your filter without falling back to copying it "just
to be safe".

permission. This is a fix for that.

a4af86c878 Track the permissions that have been given out to each picture. 
This should make it easier to know what can be done to a buffer once
it's been passed to your filter without falling back to copying it "just
to be safe".

This makes it possible to change filter callbacks (eg. to a SIMD version
on supported processors).  It also allows filters to change their own
input and output pads.
