How to map the displacement texture? I've added the Displacement Modifier to my object with a Wood texture for displace. How to change its location, rotation and scale (like you can do with image textures: Map a procedural texture like an image texture)? There are no mapping options in the Displace texture panels.

In the modifier, just switch the type to object, and then specify an empty in the drop-down box.



Here is an example blend:
