Attempts to bring all 1.12+ bed models, inventory sprites, first person and third person and ground and item frame alignment etc. back to 1.8. The only thing that isn't exact is the first person model, but based on how the 1.8 to 1.9 model transition goes, it probably is a number that is not nice like .25, etc.
To customize, replace ./assets/minecraft/textures/blocks/bed.png with the desired texture, the texture is mapped based on the default model, should work in any resolution, the default image there is the default 1.14 texture.
Let me know if there is an issue.
