Yeah, that's right - those are not declared in the IDL and are just implemented dynamically by some factories.

But most of the time they are things that are used by the UI, like for instance when doing a rotation the UI wants to show the current angle that the factory is rotating by if it was just given points as the inputs. So the rotate factory has a custom "angle" property that the UI can access to get put that number into the UI.

Or some things might analyze the input and tell the UI whether certain controls should be enabled or disabled.

Most of the time it's stuff more like that, Trim is kind of an exception.

Yeah, that's the only way you would be able to find them right now.

But Trim may be the only thing that has a custom method that is needed to be triggered for the thing to actually do its work. The vast majority of those things are just for querying stuff to put in the UI for feedback while you are moving the mouse around.
