store data per-pixbuf (in this case the iter) so this little map thing will have to do
i would try set_data on the pixbuf but i dont know if that will cause memory leaks
this would mean if a row's pixbuf animation is changed more than once then it wont be released immediately
but thats not a problem for me in this case
unordered_map doesnt compile cuz theres no hash overload, i guess
