	<brief_description>
		2D axis-aligned bounding box.
	</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.
		The 3D counterpart to [Rect2] is [AABB].

		<method name="has_no_area">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the [Rect2] is flat or empty, [code]false[/code] otherwise. See also [method get_area].
				[b]Note:[/b] If the [Rect2] has a negative size and is not flat or empty, [method has_no_area] will return [code]true[/code].

		<method name="has_point">
			<return type="bool" />
			<argument index="0" name="point" type="Vector2" />
			<description>
				Returns [code]true[/code] if the [Rect2] contains a point. By convention, the right and bottom edges of the [Rect2] are considered exclusive, so points on these edges are [b]not[/b] included.
				[b]Note:[/b] This method is not reliable for [Rect2] with a [i]negative size[/i]. Use [method abs] to get a positive sized equivalent rectangle to check for contained points.

			<description>
				Returns [code]true[/code] if the [Rect2] overlaps with [code]b[/code] (i.e. they have at least one point in common).
				If [code]include_borders[/code] is [code]true[/code], they will also be considered overlapping if their borders touch, even without intersection.
