Spaces and newlines can be inserted between the blocks, as is used in the
examples.
Position and size units are inventory slots, `X` and `Y` position the formspec
element relative to the top left of the menu or container. `W` and `H` are its
width and height values.
When displaying text which can contain formspec code, e.g. text set by a player,
use `minetest.formspec_escape`.
For coloured text you can use `minetest.colorize`.
WARNING: Minetest allows you to add elements to every single formspec instance
using player:set_formspec_prepend(), which may be the reason backgrounds are
appearing when you don't expect them to. See `no_prepend[]`
