Fit a resized group's box to its contents as drawn (TYP-919), before the step is recorded.
A group's box is derived from its contents whenever the group is built again (opening the
template, another window applying the change, an undo). A child turned between quarter turns
keeps the plain scaling and can come to reach past the box that was resized, so without this the
box would jump on reopening. Called from every gesture that resizes a group: a handle, a
multiple selection's handle, and the parameter bar's width and height. Anything that is not an
untransformed group is left alone, so callers need not ask.
