Render player's head block

[Shapaper]

有许多服务器在玩一个叫做Slimefun的插件，他不需要客户端装对应mod，插件的的机器都是通过玩家头颅实现的，我希望可以像箱子一样，提出个临时的渲染方式
Many servers are playing a plug-in called slimefun. They don't need the client to install the corresponding mod. The machines of the plug-in are realized through the player's head. I hope to propose a temporary rendering method like a boxheadhead

And it will take many more.
See the TODO list for an idea of what i am working on and the priority of this issue.

BlueMap is OpenSource, if you need this faster, do it yourself :)
