David, I checked my code again, and realized I was setting the bias

Nope. That is entirely private.
The reason I had mentioned the animatable properties is because
those visuals (including background color and the border) are not
scaled the same as your content, since they aren't cached..
Okay, thanks f

Thanks for that answer, Scott.
So, can I not make my own drawing code an animatable property? I
thought I could.
