	<description>
		[AABB] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
		It uses floating-point coordinates. The 2D counterpart to [AABB] is [Rect2].
		[b]Note:[/b] Unlike [Rect2], [AABB] does not have a variant that uses integer coordinates.

			</description>
		</method>
		<method name="abs">
			<return type="AABB" />
			<description>
				Returns an AABB with equivalent position and size, modified so that the most-negative corner is the origin and the size is positive.

		</method>
		<method name="encloses">
			<return type="bool" />
			<argument index="0" name="with" type="AABB" />
			<description>

				var box = AABB(Vector3(-3, 2, 0), Vector3(1, 1, 1))
				# position (-3, -1, 0), size (3, 4, 2), so we fit both the original AABB and Vector3(0, -1, 2)
