This is not a common feature.

good to me.

Please keep code convention. We prefer simpler way.

This looks good to me if agrresive optimization helps for better performance.

this looks wrong to me.
if user need the actual bound of the shape trees from the container, how they make it?

what happens if r is not initialized at this condition? if (pd->viewbox.w != 0 && pd->viewbox.h !=0)

do we really need 1.1.0? i have a debian installation my rockpro64 and it compiles and runs fine with 0.6.1. it can load webp images. no symbol errors, crashes or compile errors. i am thinking of dropping this down to 0.6.1 as at least empirically that is good enough (and it'd allow the CI build envs to re-enable webp again). upstream libwebp added WebPAnimDecoder in d39dc8f3cc07f0fffb73def2125ddcdf8073eafcwhich was back in september 2015. 0.6.1 came out nov 2017. so i think this is safe. possibly earlier versions might be fine too. 0.5.0 probably is the baseline for this actually (came out end of 2015 or so), but i can confirm 0.6.1 is seemingly fine. in fact i think i will drop it to 0.5.0 and then see if people complain because the anim api did come out in 0.5.0

Please check comments.

Unnecessary check. eo handles invalid objects (including nullptr) internally.
