@gnembon @altrisi this is ready for review

Ok, so I've finished the review points (finally). I also came across #1374 when looking a the pyramid code, and had to implement a workaround for it.

Note that hollow pyramids are still kinda broken if the height is less than the radius, but I have literally 0 clue how to fix that, and also my Java...

OK I looked at Firi's scarpet-edit pyramids, but the implementation was essentially the same as mine as far as I can see. The problem persists, and tbh I doubt there's...

Wait what? I swear I copied the code...

Ok, thanks to firi I've actually gotten them working: 

Well the sphere algorithm is gnembon's code, not mine. The cone code is likely due to the circle algorithm as u said, but tbh im not too bothered. And about...

all right, the reason for this is because the /draw command itself is kinda flawed (i.e. the shapes in it are). Firstly, it uses the old algorithm for circles, so...

Ok, that seems weird. I tested diamond, and it works perfectly, as expected. I think it may be because /draw can only draw hollow diamonds, and the default option for...

Still have one thing to sort out here
