Initial Lottie loader impl (Skotty) Coarse workflow: * Construction 1) build a Json tree 2) collect asset IDs (for preComp/image layer resolution) 3) "attach" pass - traverse the Json tree - build an SkSG dom, one fragment at a time - attach "animator" objects to the dom, for each animated prop 4) done, we can throw away the Json tree * For each animation tick 1) iterate over active animators and poke their respective dom nodes/attributes 2) revalidate the SkSG dom 3) draw the SkSG dom Note: post construction, things are super-simple - we just poke SkSG DOM attributes with interpolated values, and everything else is handled by SkSG (invalidation, revalidation, render).
