kdenlive uses producer_qimage instead of gdk-pixbuf.

I think the addiition of a keyframable geometry property will work.  
Qimage has some scaling methods the producer already uses. Also, it  
can accept a transformation matrix with translation for doing the  
panning:

Probably, jb already knows all of this, but he is just pacing  
himself. :-)

One idea is a a thumbnail preview of the picture with a rectangle tool  
ala a drawing tool where the aspect is constrained to the project  
profile's display aspect. Then, add keyframing.
