If col is a matrix treat the same as before
If col is a vector (of colors) then use them to color cubes by height
- If fill is TRUE this will color the filled in lower cubes differently by height
If col is a function then treat it as a palette function using max(z) as its n

Can use as.integer(cut(z, breaks = n)) to break z into n ranges (for colors)
