ITransform FR
Author: Frank Rueter - http://www.ohufx.com

Updated version of Frank Rueter's ITransform tool on nukepedia.
Mask based warper with transform controls.
Updates include:
- Channels: defaults to all channels but you can select channel to warp
- Set Center Button: Click to set to the center of the root.format or the input.format
- Black Outside Before/After: Click to apply a black outside before and/or after the warp, this can eliminate unwanted stretching edge pixels because of bounding box issues.
- Crop To Format and Add Pixels: More options for BBox management
- Mix: Using a transformMasked node instead of a transform, so the node is able to mix the warp effect Otherwise the node reacts the same way as the original ITransform node.
