<description>
A [Container] node that holds a [SubViewport], automatically setting its size.
[b]Note:[/b] Changing a SubViewportContainer's [member Control.rect_scale] will cause its contents to appear distorted. To change its visual size without causing distortion, adjust the node's margins instead (if it's not already in a container).
[b]Note:[/b] The SubViewportContainer forwards mouse-enter and mouse-exit notifications to its sub-viewports.
