few bits to sort out
- [x] make our mix of simulator/emulator consistent, settling on emulator
- [x] passing the factory in works great for just in time asset decoding, but its not amazing when you want to decode ahead of time.
- [x] couple of places left to pass this function signature through. (Question) is there a neater way to get this done, feels a bit like we are going back to parameter explosion a bit?
- [x] should do a few examples, i think the complexity grows quite a bit in this one as you add caching, or callbacks
- [x] should get the cached images/fonts to draw on init as well, either warming up cache, or jitting
- [x] examples loading assets from the bundle (also there seem to be actual asset things too? should we use those?!)
- [x] add test
- [x] re-add "preview" project & rev the preview project once this has been deployed. (do this after new ios deploy)
- [x] fix up race condition (see comment)
