Returns this [Rect2] expanded to include a given point.
Returns a copy of this [Rect2] expanded to include a given point.
[b]Example:[/b]
[codeblocks]
[gdscript]
# position (-3, 2), size (1, 1)
var rect = Rect2(Vector2(-3, 2), Vector2(1, 1))
# position (-3, -1), size (3, 4), so we fit both rect and Vector2(0, -1)
var rect2 = rect.expand(Vector2(0, -1))
[/gdscript]
[csharp]
# position (-3, 2), size (1, 1)
var rect = new Rect2(new Vector2(-3, 2), new Vector2(1, 1));
# position (-3, -1), size (3, 4), so we fit both rect and Vector2(0, -1)
var rect2 = rect.Expand(new Vector2(0, -1));

Returns [code]true[/code] if the [Rect2] contains a point.
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.
