18eb465fe8 lottie: ++optimization with object culling 
More precisely, culling the render objects by
determining if the group has no renderable objects.

Additionally, check opacity to quickly return
in the rendering process.

c20ecbcc58 lottie: introduced LottieRenderPooler 
LottieRenderPooler is designed to manages rendering
instances(paints) efficiently through a simple pooling
mechanism to resuse among the animations

This replaces the previous individusal paints implemenations
among solidfill, precomp vierport and pictures,
also fix a potential paints corruption problems.
