Returns [code]true[/code] if the [Rect2] overlaps with another.
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.
