UV Warp Modifier:

Based on patch [#30837] UV Offset Modifier
by Pawel Kowal (pkowal)

- Allows you to setup a transformation between objects to apply to UV coords.
- Option to select which axis apply to U/V.
- Option to select the UV center (needed for transformations that scale or rotate).
- Uses from/to objects in a similar way to the Warp modifier.
- Vertex group can be used to adjust influence.
