Currently when using the layout arg vpype will use the bounding box of the geometries to align it to the center and scale it to the size taking into account any margins and paper size.

It would be cool if we could use the dimensions of the svg element to align to center and scale to the paper size.

The usecase for this would be handling multi layered plots that are made up of separate svg files that are split based on plot layer it would make it easy to align to paper size and any margins while maintaining any empty space around the layers to keep consistent with other layers.

In the CLI my suggestion is to have a --no-bb flag in the layout arg
