Like iTransform, but move pixels in 3D, based on an axis, pworld and camera.

If you know iTransform, you will love this tool!
Basically, it is a 3D implementation of the idea, to transform a certain part of your image with soft transitions to the original. You can select a pmask with a tool of your choice for your CG render. The tool will make use of your camera and the CG pworld pass, to accurately transform the masked part not in 2D, but in 3D! If you manage to set a correct pivot and dial in the right transform values, you can actually alter the CG render after the fact in a plausible way, that is also stable if the CG or the camera is animated.
In this case, the upper part of the cube was rotated, just like if you would have done this in a 3D software. The method has its limits, since we are still just working with the available pixels. Internally, an STMap is generated with a Blinkscript, which is then used to modify the input. There are still minor issues with how a pivot rotation ins handled, which I will fix in the future.
