Arranges child controls in a way to preserve their aspect ratio automatically whenever the container is resized. Solves the problem where the container size is dynamic and the contents' size needs to adjust accordingly without losing proportions.
Works great with a [Panel] control. You can set [code]EXPAND[/code] on the children's size flags, so they will upscale to the ScrollContainer's size if it's larger (scroll is invisible for the chosen dimension).
