--clip-containing-box

I'm trying to clip out a section of a tileset (as opposed to clipping a bounding box around a tileset).

I tried inverting the box by swapping min and max values with --clip-bounding-box=60,60,-30,30, but I only get "Did not read any valid geometries".

Can we have a --clip-containing-box? Or can --clip-bounding-box be 'fixed' to handle this mild abuse of it's functionality?

Start by locating the --clip-bounding-box command-line option and the clipping behavior it invokes. Determine whether completion should add --clip-containing-box or extend the existing option to accept inverted bounds, then verify that a tileset section can be clipped without producing "Did not read any valid geometries".
