Summoning for hungry wizards.

General notes: Closing a path with a corner does not create a corner in the logic (for some coding reasons).

Lemon Rule: If there are more than 3 paths drawn, it will always summon a lemon.

Flour Rule: Your path need at least two corners that are not in the same direction. The path can't be closed (no separate ends). (e.g. a lightning bolt)

Water Rule: Your path must be closed, convex (no dents) and can have a maximum of one corner. (e.g. a circle)

Rolling Pin Rule: Your path must be closed and needs at least two corners in the same direction. (e.g. a triangle)

Tomato Rule: Your path has to overlap with itself at least once.

Cheese Rule: All paths need to overlap with at least one other path. It does not matter if path A overlaps B and C, or if A overlaps B, and B overlaps C.

Pineapple Rule: Your path has to be long.

Summoning the pizza: Remember that there can't be more than 3 paths (lemon rule), so you need to combine the rules for other ingredients in up to 3 paths.
Some easy combinations:
- Flour, Tomato, Pineapple - Draw a long path, with some zigzag and a loop
- Water, Tomato(, Pineapple) - Draw a large circle with a loop
Cheese has no specific rules for a single path, just let your paths overlap at some point with another path.
