By default, the node's pivot is its top-left corner. When you change its [member rotation] or [member scale], it will rotate or scale around this pivot. Set this property to [member size] / 2 to pivot around the Control's center.

Tells the parent [Container] nodes how they should resize and place the node on the X axis. Use one of the [enum SizeFlags] constants to change the flags. See the constants to learn what each does.
