[css-paint-api] Registering properties from within a worklet.

I have a paint worklet that has a few color properties that I'd like to animate. But I don't like that I have to declare the property types in a separate css file. I'd prefer them in the same worker file so they are nicely bundled.
Maybe I'm missing something but I don't think there is currently any way to register properties from within a worklet.
