Can Pictures be used for performance improvements?

[AdamGerthel]

I'm currently attempting to improve performance of a 9-slice solution (see #2818 to get a better idea), and I'm trying to wrap my head around whether I could utilize createPicture to draw my button backgrounds, store the output somewhere, and then re-use the picture in future renders (when visually related props are the same).

My questions are:

1. Does this make sense?
2. Does Picture support images?

yes that makes a lot of sense, I am wondering if the atlas API would be a good API to draw the button, or it looks like this API might be even more of a fit: https://api.skia.org/classSkCanvas.html#ab8a724321360f9f71b409f8d11172628 (we don't expose it but we could if there is a compelling use case for it.
Or maybe this one: https://api.skia.org/classSkCanvas.html#a3a9a10b43dcffdac586ca21b853627b3?

drawImageNine definitely sounds exactly what I would want. It's precisely what I'm doing manually.
