	<brief_description>
		2D axis-aligned bounding box using floating point coordinates.
	</brief_description>
	<description>
		[Rect2] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
		It uses floating-point coordinates. If you need integer coordinates, use [Rect2i] instead.
		The 3D counterpart to [Rect2] is [AABB].
