+			If enabled, oversampling for this [CanvasItem] is automatically adjusted with scale. This makes fonts and [DPITexture] images automatically re-render to match the actual scale they are drawn at, for crisper visuals. This has a performance impact on the CPU every time the node's scale changes, so it is disabled by default.
+			[b]Note:[/b] For [Control] nodes with [member Control.offset_transform_enabled] set to [code]true[/code], scale-based oversampling is only effective if [member Control.offset_transform_visual_only] is [code]false[/code]. This ensures there is no performance overhead when using visual-only offset transforms (as often used in animations).
