More compositing goodies.

- Texture Node
Allows to use any Blender Texture block as input for masks or color
blending. The texture node doesn't generate a real image, but adjusts to
the size as mapped with during an operation. So it won't work to use it
as Image input for Blur or Filter nodes.

Note; the Vector inputs for this node only work with manual input now!

- Translation Node
Give any image an offset in X or Y direction

For the Texture node to work, I needed to move the central 'pixel
processor' up one level... to allow differently sized images to merge
and allow 'procedural images' without size.
