“Native” … is also code 
In the next step this will be wrapped in an extension and offered as minified code that runs on every scene load. Much more can’t be offered at this point. The code then kind of disappears into a modular “Runtime” extension. I wish extensions could have more capabilities in the GUI itself because making them keeps the base runtime slim and one could modularize features. But in this case I would be very surprised if this doesn’t end up in the core GUI and runtime.
The extension at this point only requires to be run on scene load and looks for “[data-clip-path]” (meaning an attribute on the element) containing the classname of the vector tool outline. Simple… no coding required!
