Scale the current WorldEdit positions and region by a factor of positive integer <factor> with position 1 as the origin.

//scale 2

//scale 1

//scale 10

Scales the region defined by positions `pos1` and `pos2` by an factor of positive integer `factor` with `pos1` as the origin.

Returns the number of nodes scaled, the new scaled position 1, and the new scaled position 2.

Returns the number of nodes transposed, the new transposed position 1, and the new transposed position 2.
