Make more block like cushion

I think the cushion is a BIG change in what Minecraft can do with blocks and entities and that's why I think some block should start to use this system (in future update, when it will not make fps drop as much as now)

I'll take the idea from 2 peoples of the community who give this ideas :
- Make all block like cushion
- Item frames like cushion

For me, not only the item frame should be like the cushion but also all the non full "blocky" one like the pot. I saw a beautiful idea with pots on shelf mushroom who could be wonderful and very creative !

Also banners, candles, snow, lantern, all type of vines, chain, all carpet, the amethyst bud, bed, mob heads or even leaf on the ground ! 

I'll be honest, with all this entities on a world, it will make A LOT of fps problem but I think it can be resolve by just making, naturally generated item, non entities and when the player collect them, act like an entity when place BY THE PLAYER
