Returns what type of hull is at the position x, y on the specified ship. The coordinates are computed from the left-bottom corner and are zero-based. See this example created by planetfall.

The returned value is defined by this table. Decimal value is next to hexadecimal constants larger than 10 for clarity.

The function returns -1 if the ship id is invalid or the coordinates are out of range. This also ignores whether or not the ship is damaged, and returns data from the ship's plan instead.
