Beer that looks like beer

[Frank_Stein]

I once made an abandoned pr that visually had different states of matter layer on top of each other while in beakers, to add beer foam I think it'd make sense for it to be by a more robust version of that. Code the system to where you can have chems have different layers in containers based mostly off of state of matter. Also add a "don't visually mix with other chems" var and a "change the default positioning (ie gas on bottom)" var so you can have stuff like a visually distinct liquid beer foam chem which goes on top of liquids that occurs when you dispense beer or a solid on top of gas ie frobscottle. I have no intents on coding this but if anyone wants to look at my admittedly messy code and pick it up please do

That would be nice in general for cocktails. Beer foam is a novel route to take, could be something that forms whenever beer is dispensed and gradually breaks down into beer.

You can now have an ideal foam to beer ratio for effects, and even get into forensics where you could estimate how long drinks were poured based on foam present
