Image Node now supports animations as well. Press the 'Sequence' Icon in
the node to see the options:
- Frs: the amount of images involved in the sequence
- SFra: start frame, the Blender frame number
- First: the number in the name of the first image in the sequence
- Cycl: make the sequence go cyclic
The images are refreshed on each call to execute the node tree, but not
on advancing frames in Blender... I suspect that might make it to slow now,
will first have to code nice threaded/optimized updates in compositor.
