Control for holding [SubViewport]s.
A [Container] node that holds a [SubViewport], automatically setting its size.
- If [code]true[/code], the sub-viewport will be scaled to the control's size.
- Divides the sub-viewport's effective resolution by this value while preserving its scale. This can be used to speed up rendering. For example, a 1280×720 sub-viewport with [member stretch_shrink] set to [code]2[/code] will be rendered at 640×360 while occupying the same size in the container. [b]Note:[/b] [member stretch] must be [code]true[/code] for this property to work.
